Lagoon Pouch Bag: Free Crochet Pattern

There is something quietly magical about a bag that looks like it was pulled from the depths of a tidal pool. The Lagoon Pouch Bag is exactly that kind of project — a small, structured pouch with a texture that ripples and shifts the way sunlight moves through shallow water. Whether you are a seasoned crocheter looking for your next satisfying make or someone who has finished a few basics and is ready to level up, this pattern is designed to be worked through with confidence and clarity. Best of all, it is completely free.

In this post, you will find the complete pattern, notes on materials, stitch guidance, and finishing tips to help you create a pouch that looks polished enough to sell at a craft market or gift to someone who appreciates handmade things. Pour yourself something warm, grab your hooks, and let’s get into it.

What Is the Lagoon Pouch Bag?

The Lagoon Pouch Bag is a small zippered or drawstring pouch — depending on which closure you prefer — made using a combination of basic and textured crochet stitches that create a dimensional, almost woven-looking surface. The design draws its name from the layered, tranquil look of a coastal lagoon, with stitches that form subtle waves and a palette that works beautifully in ocean-inspired blues and greens, though it translates just as well into earthy neutrals, deep burgundies, or soft blush tones.

The finished size is approximately 7 inches wide by 5 inches tall (excluding straps or handles), making it ideal for use as a makeup bag, a coin purse, a travel accessories pouch, or a small everyday bag to tuck inside a larger tote. The structure is firm enough to hold its shape but flexible enough to compress in a bag without losing its look.

This is an intermediate-level pattern. If you are comfortable with single crochet, half double crochet, and working in rows, you will handle this project well. There is one textured stitch that requires a little practice, but it is explained fully below and is easier than it looks once you try a swatch.

Materials You Will Need

Before you begin, gather the following:

Yarn: Approximately 150 to 200 yards of worsted weight yarn (size 4). Cotton yarn is strongly recommended for this project because it gives the bag structure and makes the textured stitches pop clearly. A cotton-acrylic blend also works well. For the color palette shown in the original design, choose a main color (MC) in a medium teal or slate blue and a contrast color (CC) in cream, ivory, or light sand. You can absolutely use a single color throughout if you prefer a more minimal look — the texture carries the design beautifully on its own.

Hook: 4.0mm crochet hook (G hook). If your gauge is typically tight, go up to a 4.5mm hook.

Other supplies:

• Tapestry needle for weaving in ends
• Scissors
• One 7-inch zipper in a color that complements your yarn, OR approximately 1 yard of ribbon or cord for a drawstring closure
• Stitch markers (optional but helpful)
• Straight pins for blocking if desired
• A piece of thin plastic canvas or interfacing to stiffen the base (optional but recommended for structure)

Gauge: 16 stitches and 20 rows = 4 inches in single crochet with worsted weight cotton and a 4.0mm hook. Gauge is not critical for this project since we are not working to an exact garment size, but keeping your tension consistent will give you a neater, more even surface.

Abbreviations and Stitch Guide

The following abbreviations are used throughout this pattern. All are written in US crochet terminology.

ch — chain
sl st — slip stitch
sc — single crochet
hdc — half double crochet
dc — double crochet
bpsc — back post single crochet: insert your hook from back to front around the post of the indicated stitch from the previous row, yarn over and pull up a loop, yarn over and draw through both loops on hook
fpsc — front post single crochet: insert your hook from front to back around the post of the indicated stitch from the previous row, yarn over and pull up a loop, yarn over and draw through both loops on hook
RS — right side
WS — wrong side
rep — repeat
sk — skip
st(s) — stitch(es)

The textured stitch pattern in this bag alternates between fpsc and bpsc stitches, which creates the raised, ridged, lagoon-like surface. Working around the post of the stitch rather than through the top loops pushes the previous rows forward or backward to form the ripple effect. If you have never worked post stitches before, take five minutes to practice on a small swatch before beginning the bag. You will find that the technique becomes intuitive very quickly.

Pattern Instructions

Part One: The Bag Body (Make Two Panels)

The Lagoon Pouch Bag is constructed in two flat panels that are joined together along the sides and bottom. This construction method makes it easy to insert lining, add interfacing, or include an interior pocket if you wish.

Foundation Row: Using your MC yarn, chain 30. (This gives you a starting width of approximately 7 inches.)

Row 1 (RS): Sc in the second chain from hook and in each chain across. (29 sc) Turn.

Row 2 (WS): Ch 1, sc in each st across. (29 sc) Turn.

Row 3 (RS) — Begin Texture Pattern: Ch 1. Fpsc around the post of the next st, bpsc around the post of the next st. Repeat from to across, ending with 1 sc in the last st if needed to complete the row. (29 sts) Turn.

Row 4 (WS): Ch 1. Bpsc around the post of the next st, fpsc around the post of the next st. Repeat across, ending with 1 sc in the last st if needed. (29 sts) Turn.

Rows 3 and 4 form the texture repeat. Continue working these two rows alternately until your panel measures approximately 5 inches from the foundation row, ending on a WS row. This will typically be around 20 to 24 rows depending on your tension.

Top Edge (RS): Ch 1, sc across the top of the panel. Fasten off and weave in ends.

Make a second identical panel.

Part Two: The Base Strip (Optional but Recommended)

Adding a narrow base strip gives the bag a flat, structured bottom and helps it sit upright when set down. If you prefer a completely flat pouch, you can skip this step and simply seam the two panels together at the bottom.

Foundation Row: Using your MC yarn, chain 10.

Row 1: Sc in the second chain from hook and in each chain across. (9 sc) Turn.

Rows 2 through 28: Ch 1, sc in each st across. Turn.

The base strip should measure approximately 7 inches long when complete. Fasten off, leaving a long tail for seaming.

Part Three: Joining the Panels

Place your two panels with wrong sides facing each other (right sides facing out). If you are adding the base strip, position it between the two panels at the bottom, aligning it flush with the lower edge.

Using your MC yarn and a tapestry needle or a slip stitch join with your crochet hook, seam the two panels together along the bottom edge and both side edges, incorporating the base strip as you work across the bottom. Leave the top edge open.

If you are working the slip stitch join with your hook, insert the hook through both layers of fabric through the top loops of matching stitches on both panels, yarn over and draw through, then draw through the loop on your hook. Work across consistently for a neat, even seam. This join is visible from the outside and can be a design feature in your contrast color if you like.

Before closing the final side seam entirely, insert your plastic canvas or interfacing into the base of the bag if you are using it. Trim it to fit snugly and then complete the seam.

Part Four: Top Edge Finishing

Once your panels are joined, work a single round of sc around the entire top opening of the bag, working through both layers at the corners and along the sides to stabilize the edge. Join with a sl st to the first sc. Fasten off.

This creates a clean, firm edge that will support the zipper or drawstring without stretching.

Part Five: Adding the Closure

Zipper Option: Lay the bag flat with the top edge open and the right side facing up. Position your 7-inch zipper face-down along the inside of the top edge, with the zipper teeth aligned just below the top row of single crochet. Use straight pins to hold it in place. With a tapestry needle and a length of matching yarn or coordinating thread, whip stitch the zipper tape to the inside top edge of the bag on both sides. Work carefully and evenly, keeping your stitches close together for security. Once both sides are attached, open and close the zipper a few times to check the placement before trimming any excess zipper tape and sealing the ends with a dab of fabric glue or a few hand stitches.

Drawstring Option: If you prefer a drawstring closure, work one additional row at the top of the bag before finishing. On this row, create a series of evenly spaced eyelets by working ch 2, skip 2 sts, sc in next 3 sts across the round, then joining with a sl st. Fasten off and weave in ends. Thread your ribbon or cord through the eyelets using a tapestry needle or a small safety pin, and tie the ends together in a bow or knot at one side.

Part Six: Strap or Handle (Optional)

The Lagoon Pouch Bag works beautifully as a standalone clutch or a bag-within-a-bag, but if you want to add a simple strap, here is a quick option.

Wrist Loop: Chain 40 with your MC yarn. Sl st in the first chain to form a loop. Fasten off, leaving a tail. Attach the loop securely to one side seam of the bag by threading the tail through the seam and knotting it firmly on the inside. This creates a small wrist loop that is practical without adding bulk.

Short Carry Strap: Chain 80. Row 1: Sc in the second chain from hook and in each chain across. (79 sc) Row 2: Ch 1, sl st in each st across. Fasten off. This creates a narrow flat strap that you can attach to both side seams for a crossbody or shoulder option. Reinforce the attachment points by stitching through multiple times.

Color Work Ideas

One of the joys of this pattern is how differently it reads in various color combinations. Here are a few palettes worth trying.

Coastal Classic: Main color in deep ocean teal, contrast seam in warm ivory. The color combination feels coastal and fresh and works for any season.

Desert Sand: Dusty rose main color with terracotta seam stitching. This palette reads warm and earthy and has a lovely boho quality.

Midnight Garden: Deep forest green main color with a black seam. Moody, sophisticated, and striking in a monochromatic way.

Sunrise Pouch: Soft butter yellow main color with peach or blush seam stitching. Light, cheerful, and perfect for spring markets or gifting.

If you want to incorporate your contrast color more prominently, you can work every fourth row in CC instead of MC, carrying the yarn loosely up the side of the work. This creates a striped variation that still shows the texture pattern beautifully.

Tips for a Polished Finish

A few small habits make a big difference in the final result of this project.

Work your foundation chain loosely. A tight chain at the base will cause the bottom edge of your bag to pucker and pull inward. If your foundation chains tend to be tight, go up one hook size for just the chain and then return to your working hook for Row 1.

Block your panels before seaming. Cotton yarn responds beautifully to wet blocking. Wet your finished panels, gently squeeze out excess water, and pin them to the correct dimensions on a foam mat. Allow them to dry completely before joining. This step makes the seaming process smoother and gives the finished bag a much more professional look.

Weave in your ends securely. Because this bag will be opened and closed repeatedly and will see regular use, take extra care when weaving in your tails. Run the yarn through several stitches in one direction and then backtrack through a few stitches in the other direction before trimming. This keeps the ends from working their way loose over time.

Use sharp scissors when trimming the zipper tape. A clean cut prevents fraying and keeps the inside of the bag looking tidy even if you choose not to line it.

Lining the Bag (Optional but Lovely)

Adding a fabric lining takes this pouch from handmade to heirloom. Choose a cotton fabric in a print or solid that complements your yarn color.

Cut two pieces of fabric to the same dimensions as your finished panels (approximately 7 inches wide by 5 inches tall) plus a half-inch seam allowance on all sides. Sew the two fabric pieces together along the bottom and both sides with right sides facing, leaving the top open. Press the seams open.

Fold the top raw edge of the lining down by a half inch and press. Slip the lining inside the bag with wrong sides of the lining facing the wrong sides of the crochet panels. Pin the folded top edge of the lining just below the zipper or drawstring row. Whip stitch the lining to the inside of the bag using a sewing needle and coordinating thread, catching the folded edge with each stitch. Press lightly with a warm iron if needed.

A lining adds durability, prevents small items from catching in the crochet fabric, and gives the bag a clean, finished interior that makes it feel genuinely luxurious.

Pattern Notes and Sizing Adjustments

The chain count in this pattern is a multiple of 2 plus 1, which keeps the post stitch pattern working out evenly across each row. To make a larger bag, simply increase your starting chain by any even number. A chain of 40 gives you a bag approximately 9.5 inches wide. A chain of 20 gives you a small coin purse approximately 4.5 inches wide. The row count scales accordingly — continue working the texture repeat until the panel height matches the width in proportion, or adjust to whatever dimensions suit your purpose.

For a larger tote-style bag, use bulky weight yarn (size 5 or 6) and a 6mm hook, and add a longer and wider strap. The texture pattern translates well to bulkier yarn and works up very quickly at that scale.

Frequently Asked Questions

Can I use acrylic yarn for this pattern? Yes, absolutely. Acrylic will produce a softer, more drapey result than cotton, which changes the character of the bag from structured to flexible. If you prefer a firmer result with acrylic, consider adding a layer of fabric interfacing to the inside of the panels before joining them.

Is this pattern beginner-friendly? It sits comfortably at the intermediate level because of the post stitches. If you are a confident beginner who has completed several single crochet projects and is ready to try something new, this is a great next step. Set aside time to practice the post stitches on a small swatch first and you will feel prepared.

How do I care for the finished bag? If you used cotton yarn, the bag can be hand-washed in cool water with a gentle soap and laid flat to dry. Avoid wringing or twisting. If you used an acrylic or blend, follow the care instructions on your yarn label.

Can I sell items made from this pattern? Yes. This is a free pattern shared for both personal and small-scale commercial use. If you sell finished bags made from this pattern, a credit or tag is always appreciated but not required.

A Few Final Thoughts

The Lagoon Pouch Bag is one of those projects that rewards you every step of the way. The texture builds up satisfyingly row by row, the seaming is straightforward, and the moment you attach the zipper and zip it shut for the first time, there is a particular kind of crafter’s joy that is hard to describe but easy to recognize. It is the feeling of having made something genuinely useful and genuinely beautiful.
