Knitted Satchel Bag Free Pattern: A Complete Step-by-Step Guide

There is something deeply satisfying about carrying a bag you made yourself. The texture of the yarn beneath your fingers, the weight of a finished object you brought into existence from nothing but fiber and two needles — it is one of those crafting pleasures that never gets old. If you have been searching for a knitted satchel bag free pattern that actually delivers clear instructions, a beautiful finished result, and room to customize, you have landed in exactly the right place.

This pattern is designed for knitters with intermediate experience, though adventurous beginners who are comfortable with basic stitches and simple shaping will find it approachable with a little patience. The finished bag has a classic satchel silhouette — structured sides, a flap closure, and a long adjustable strap — making it practical enough for daily use while remaining stylish enough to draw compliments wherever you take it.

About This Pattern

The satchel style has been a wardrobe staple for centuries, originally designed as a practical carry-all for students and travelers. What makes the knitted version so appealing is the combination of warmth, texture, and personality that no manufactured bag can replicate. Every stitch you place is intentional. Every row tells the story of an afternoon spent crafting something that will last.

This particular design features a main body worked in a simple seed stitch that gives the fabric beautiful visual interest and a firm, stable drape. Seed stitch is forgiving to work and creates a reversible fabric with a lovely bumpy texture that photographs wonderfully. The flap is shaped with a slight curve, the gusset gives the bag depth and structure, and the strap is long enough to wear cross-body or over the shoulder.

The finished bag measures approximately 11 inches wide, 9 inches tall at the front, and 3 inches deep at the gusset — a generous size that fits a wallet, phone, keys, a small notebook, and all the other essentials of modern life.

Materials You Will Need

Before you cast on, gather everything you need so the process flows smoothly from start to finish.

Yarn: Approximately 400 to 500 yards of a worsted weight yarn (US weight 4). Choose a yarn with some structure to it — a wool-blend, cotton, or a sturdy acrylic all work beautifully. Avoid very soft, drapey yarns like bamboo or Tencel blends, as they will not hold the satchel shape as well. A good twist in the yarn helps the seed stitch definition really pop.

Needles: US size 7 (4.5mm) straight or circular needles. You can use circular needles to work flat, which many knitters prefer for a wider fabric. You will also need a double-pointed needle or a short circular in the same size for picking up stitches along the sides.

Notions: A tapestry needle for seaming and weaving in ends, stitch markers, a tape measure, one large magnetic snap closure or a button with a corresponding loop, a small piece of iron-on interfacing or stiff stabilizer for lining the bottom (optional but highly recommended for structure), and scissors.

Gauge: 18 stitches and 28 rows over 4 inches in seed stitch on US size 7 needles. Take the time to swatch and check your gauge. Because this is a bag and not a garment, gauge does not need to be perfect, but being significantly off will change your finished dimensions noticeably.

Understanding Seed Stitch

If you are not already familiar with seed stitch, it is worth spending a moment on it before diving in. Seed stitch is worked by alternating knit and purl stitches across every row, and then on the following row, you work the opposite stitch over each one — meaning you purl over a knit and knit over a purl. This creates a checkerboard of raised bumps rather than the vertical ribbing of knit-one-purl-one rib.

For an even number of stitches, the seed stitch repeat works like this: Row 1 is knit 1, purl 1 across. Row 2 is also knit 1, purl 1 across. Because you are working flat and turning your work, the row-two instruction automatically places a knit over a purl and vice versa.

For an odd number of stitches, every row begins and ends with knit 1, and the pattern self-corrects without any need to track rows. Many knitters find the odd-stitch version easier to memorize and work without counting.

This pattern uses an odd stitch count for the main body panels, so you only need to remember one rule: every row starts and ends with knit 1, and you alternate knit and purl across the rest.

Pattern Instructions

Abbreviations

CO = cast on, BO = bind off, K = knit, P = purl, RS = right side, WS = wrong side, rep = repeat, st(s) = stitch(es), yo = yarn over, k2tog = knit two together, pm = place marker, sm = slip marker.

Front and Back Panels (Make Two)

Cast on 51 stitches using the long-tail cast on or your preferred method. The long-tail cast on creates a firm, neat edge that works beautifully at the bottom of a bag.

Seed stitch row (all rows): K1, (P1, K1) across to end.

Work in seed stitch as established until the piece measures 9 inches from the cast-on edge. Bind off all stitches in pattern, meaning you work the bind off in seed stitch rather than knitting across — this keeps the top edge as stretchy and even as the rest of the fabric.

Make a second identical panel.

Gusset and Strap (Worked as One Piece)

This is one of the most satisfying parts of this design. The gusset and strap are worked as a single long strip that runs around the bottom and sides of the bag and then continues up into the strap. This eliminates seams at the corners and creates a clean, professional finish.

Cast on 15 stitches.

Work in seed stitch as established until the strip measures approximately 60 inches. This length accounts for the gusset (which will travel across the bottom, 11 inches, and up both sides, 9 inches each, for a total of 29 inches) plus the full strap length of approximately 48 inches. If you prefer a longer strap for cross-body wear, add extra length here.

Bind off all stitches in pattern.

Fold the strip in half to find the center point and mark it with a stitch marker or small piece of waste yarn. This center point will align with the bottom center of the bag when you seam everything together.

Flap

The flap is worked separately and sewn to the back panel after blocking. Its curved lower edge is created with a simple decrease section that shapes the corners into a rounded point — the classic satchel flap silhouette.

Cast on 51 stitches.

Work in seed stitch for 5 inches, ending after a WS row.

Begin shaping:

Row 1 (RS): Work in seed stitch to the last 3 stitches, k2tog, K1.
Row 2 (WS): K1, k2tog (working in pattern), work in seed stitch to end.

Repeat these two rows until 25 stitches remain. At this point the flap tapers to a central column.

Bind off remaining stitches in pattern.

Inner Pocket (Optional but Recommended)

A simple flat pocket adds enormous functionality to this bag. Cast on 31 stitches and work in seed stitch for 5 inches. Bind off in pattern. This pocket will be seamed to the inside of the front or back panel before the bag is assembled. Position it centered and approximately 1.5 inches from the top edge of the inside panel.

Finishing and Assembly

Finishing is where the bag truly comes together, and taking your time here makes all the difference between something that looks handmade in the best possible way and something that simply looks unfinished.

Blocking: Before assembly, wet block all pieces. Soak them in cool water for 15 to 20 minutes, gently press out the excess moisture in a clean towel, and lay them flat to dry. Blocking evens out the stitches, opens up the seed stitch texture, and brings the fabric to its final dimensions. This step is not optional if you want a polished result.

Seaming the gusset: Lay one front panel flat with the right side facing up. Pin the gusset strip to the edges of the panel, starting at the center bottom marker and working around the two sides. Use a mattress stitch for the seams, which creates an invisible join when worked correctly. Take your time working around the lower corners, easing the gusset fabric gently so it lies flat without puckering.

Once the front panel is seamed, repeat the process with the back panel on the opposite side of the gusset. At this point your bag will be a three-dimensional object for the first time, and there is a genuinely exciting moment when you first hold it up and see the shape.

Attaching the flap: Position the flap along the top back edge of the bag, right sides facing each other, and sew across the straight cast-on edge with mattress stitch or a simple whipstitch. The flap should hang down over the front of the bag when folded into position.

Adding the closure: Mark the position of your magnetic snap on the underside of the flap, centered and approximately half an inch from the pointed end. Mark the corresponding position on the front panel. Install the snap according to the manufacturer’s instructions — most magnetic snaps require cutting two small slits through the fabric, threading the prongs through, and bending them flat on the wrong side. If you are using a button instead, sew it to the front panel and work a small yarn loop or purchase a small cord loop for the flap end.

Reinforcing the bottom: Cut a piece of stabilizer slightly smaller than the bottom of the bag (approximately 10 by 2.5 inches) and slide it inside along the gusset bottom. This keeps the base flat and prevents the bag from sagging. You can stitch it in place with a few hand stitches through the gusset fabric if you want a more permanent solution.

Weave in all ends carefully and securely. Because this bag will be used daily and subjected to real wear, take extra care with your ends — weave them in multiple directions through the seed stitch fabric to anchor them well.

Customization Ideas

One of the great pleasures of working from a free pattern is the invitation to make it your own. Here are some ideas to spark your creativity.

Colorwork: This design translates beautifully into two-color stripes. Work the front and back panels in alternating stripes of two or three colors, keeping the gusset in a single neutral shade to tie everything together. Even simple two-row stripes in alternating colors create a striking effect in seed stitch.

Cables: For a more textured, heritage look, substitute a central cable panel into the front and back pieces. Replace the center 15 stitches of the seed stitch with a 6-stitch cable repeated every 6 rows, keeping the seed stitch border on either side. This requires a cable needle and a little planning but creates a truly impressive result.

Lining: Adding a fabric lining transforms the bag from a beautiful object into a truly practical everyday companion. Cut a lining from a sturdy cotton or canvas in coordinating or contrasting fabric, stitch it up using a sewing machine, and hand-stitch it inside the bag, turning under the raw top edge and catching it just below the bind-off row.

Hardware: Swapping the yarn strap for a chain or leather strap gives the bag a completely different personality. Simply omit the strap section from your gusset strip, bind off at 29 inches, and attach a D-ring or lobster clasp hardware at each side seam to hold a purchased strap.

Size adjustments: Scaling the bag up or down is straightforward with this pattern. For every inch you want to add or subtract in width, adjust your cast-on by approximately 4 stitches. For height changes, adjust row count. Keep in mind that adding significant size means you will need more yarn, so buy extra.

Tips for Success

A few practical notes that will save you time and frustration as you work through this project.

Work your gauge swatch in seed stitch, not stockinette. These two stitch patterns can behave quite differently on the same needles, and your gauge swatch should reflect the actual stitch you will be using throughout the bag.

Keep a consistent tension throughout the project. Because the front, back, gusset, and flap are all worked separately and then joined, inconsistent tension can make the pieces difficult to seam neatly. If you notice your tension varying when you pick the project back up after a break, work a few extra rows before you rejoin where you left off, then undo those test rows.

Use stitch markers at the center points of each panel and the gusset strip. Having clear reference points when seaming makes the assembly much more intuitive.

Do not rush the seaming. Seriously — this is the advice every experienced knitter will give you. The knitting goes quickly once you are in the rhythm of seed stitch, but the assembly deserves an equal investment of time and care.

Care Instructions

Depending on your yarn choice, care will vary. If you used a superwash wool or acrylic, the bag can typically be machine washed on a gentle cycle in a mesh laundry bag. Pure wool should be hand washed in cool water with a gentle wool wash and laid flat to dry. Cotton and cotton blends can usually tolerate a machine wash on cold. When in doubt, check the care label on your yarn ball band and follow those recommendations.

Reshape the bag while it is still damp after washing and allow it to dry completely before using it again. This keeps the structure looking its best over years of use.

A Few Final Thoughts

A knitted satchel bag is the kind of project that sits in that sweet spot of knitting ambition — complex enough to be genuinely satisfying, straightforward enough that you can make real progress in an evening. It is a project that teaches seaming, shaping, and the joy of a beautiful workhorse stitch all at once. And at the end, you have something you will actually use, something that starts conversations, something you made with your own hands.

Whether you follow this pattern exactly, swap in your favorite colors, or use it as a jumping-off point for your own design explorations, we hope it brings you many hours of satisfying knitting. Take your time, enjoy the process, and do not forget to block before seaming — your future self will thank you every time you admire those perfectly even stitches.

Happy knitting.
