How to Crochet a Mini Frame Bag – Complete Guide for the 18-Sample Pattern

Few crochet projects combine elegance and practicality quite like a mini frame bag. With its structured silhouette, satisfying snap closure, and endless customization potential, this little purse has become a beloved staple in the handmade accessories world. Whether you’re picking up a hook for the first time or you’re a seasoned crocheter looking to expand your pattern library, this complete guide walks you through everything you need to know to crochet a beautiful mini frame bag using the popular 18-sample pattern — from choosing your materials to finishing your final seam.

What Is a Mini Frame Bag?

A mini frame bag, sometimes called a coin purse frame bag or a kissing clasp purse, is a small structured bag built around a metal purse frame. The frame — typically made of brass or silver-toned metal — features a hinged opening with a satisfying “click” closure that gives the bag its characteristic shape and rigidity. When the bag is open, the two halves spread apart like a mouth, making it easy to access the interior. When snapped shut, the frame locks the bag into a smooth, rounded form.

The “mini” version typically measures somewhere between 10 and 15 centimeters across, making it perfect for carrying coins, lip balm, a few cards, or small daily essentials. Despite its modest size, a crocheted mini frame bag is a showstopper. The texture of the yarn against the polished frame creates a beautiful contrast, and because the bag is small, it’s a wonderful canvas for experimenting with color combinations, stitch patterns, and decorative embellishments.

The 18-sample pattern specifically refers to a structured set of design variations — typically 18 distinct colorway and stitch combinations — that allow makers to produce a cohesive collection or simply choose the style that suits them best. These patterns have circulated widely in Vietnamese craft communities and have since gained popularity globally for their clarity and versatility.

Why Crochet a Mini Frame Bag?

Before we get into the how-to, it’s worth pausing on the why. There are a lot of crochet projects out there. What makes this one worth your time?

First, it’s genuinely achievable for intermediate beginners. Unlike blankets that require hours of repetitive stitching, or amigurumi that demands precise tension and careful shaping, the mini frame bag gives you a finished, functional object in a relatively short time. A dedicated crocheter can complete one bag in an afternoon.

Second, it teaches useful skills. Crocheting in the round, reading a charted pattern, working with stiffening agents, attaching your work to a hardware component — all of these are techniques that will serve you across countless other projects. The mini frame bag is, in a sense, a crochet finishing school in miniature.

Third, the results are marketable. Handmade frame bags sell beautifully at craft fairs, on Etsy, and through social media shops. Because the materials are inexpensive and the project is quick, the profit margin is favorable. If you’re looking to add something to a handmade product line, this is a smart choice.

And fourth — let’s be honest — they are absolutely charming. There’s something irresistible about a tiny, perfectly formed bag that clicks shut with a satisfying snap.

Materials You Will Need

Gathering the right materials before you start makes the whole process smoother. Here’s what you’ll need for the standard 18-sample mini frame bag pattern.

Yarn: The pattern works best with a cotton yarn or a cotton-blend, typically in weight category 3 (light) or category 4 (medium/worsted). Cotton gives the finished bag structure and holds its shape well, which is especially important since the bag needs to sit neatly against the metal frame. You’ll need approximately 50–80 grams per bag, depending on the size of your frame. For the 18-sample collection, you’ll want to gather a variety of colors — the pattern plays beautifully with contrasting shades, tonal gradients, and even marled or variegated yarns.

Crochet Hook: For category 3 yarn, a 2.5mm to 3mm hook is standard. For category 4, use a 3.5mm to 4mm hook. The key is to crochet firmly enough that the fabric has body. A too-loose gauge produces a floppy bag that won’t hold its shape against the frame. Do a quick swatch and see how the fabric feels — it should be dense but not stiff.

Mini Purse Frame: Look for frames that are between 10 and 15 centimeters wide. Frames come in several opening styles: sew-in (with holes along the edge for attaching your crochet), glue-in (where the fabric is inserted into a channel and secured with adhesive), and wrap-style. The most beginner-friendly for crochet is the sew-in frame, as you can attach your work with a simple whip stitch. Many craft suppliers and online marketplaces sell these frames affordably, often in multipacks. For the 18-sample pattern, a consistent frame size across all samples gives the collection a unified look.

Tapestry Needle: You’ll need this for weaving in ends and for sewing the crochet fabric to the frame. Use one with a large eye that accommodates your yarn weight.

Stitch Markers: These are optional but helpful, especially when you’re working in the round and need to track the beginning of each round.

Scissors: A small, sharp pair works best for yarn.

Fabric Stiffener (optional): Some makers like to lightly stiffen their finished bags to give them extra structure. A light spritz of starch spray or a diluted solution of craft glue can work well. This is particularly useful if you’re making the bag as a gift or for sale, as it helps the bag maintain its shape over time.

Lining Fabric (optional): A small piece of cotton or satin lining gives the interior a polished, professional look. It also prevents small items from slipping through the stitches. You’ll need only a small rectangle — typically the same dimensions as the bag’s body — and basic sewing supplies to attach it.

Understanding the 18-Sample Pattern Structure

The 18-sample format is essentially a pattern collection. Each sample represents a variation — different color combinations, different surface textures, or different decorative motifs — all constructed on the same foundational shape. Think of the base pattern as a template, and the 18 samples as different outfits you can put on that template.

The bag body is typically crocheted in two halves, worked separately and then joined, or worked in a continuous oval from the base up. The pattern usually starts with a foundation chain that creates the oval bottom of the bag, with increases worked at each end of the oval to create the rounded shape. As you work upward, the increases stop and the sides grow straight, building the walls of the bag. Near the top, the fabric is shaped to match the contour of the frame.

Each of the 18 samples in the collection typically specifies:

The colorway, including the main color and any accent colors used for edging, stripes, or motifs. The stitch pattern, whether it’s a simple single crochet that gives a dense, clean surface, a moss stitch or linen stitch for light texture, a shell stitch border for decorative flair, or a surface slip stitch for added dimension. Any embellishments such as a flower motif, a small bow, a chain tassel, or a button accent. The finishing treatment, including whether the sample uses a liner, a particular sewing attachment method, or a stiffening technique.

Working through all 18 samples is a rewarding project arc. Many makers choose to complete all 18 as a set — sometimes displayed together as a craft demonstration or sold as a collection. Others pick two or three favorites and repeat them in different colorways.

Step-by-Step: How to Crochet the Mini Frame Bag Base Pattern

Now let’s walk through the actual crochet process for a standard mini frame bag in the 18-sample style. This is the foundational pattern upon which all 18 variations are built.

Step 1: Create the Foundation Chain

With your chosen yarn and hook, create a foundation chain. For a 12cm frame, start with a chain of 20 stitches. This chain will form the long axis of the oval base.

Step 2: Work the First Round

Single crochet into the second chain from the hook and in each chain across — you’ll work 18 single crochets along the top of the chain. At the end of the chain, work 3 single crochets into the final chain stitch to turn the corner. Now work back along the underside of the foundation chain, working 1 single crochet into each chain stitch. At the other end, work 2 single crochets into the same stitch where you began. Place a stitch marker to mark the beginning of the round. You now have an oval with 42 stitches total.

Step 3: Increase Rounds

For the next two to three rounds, work increases at the curved ends of the oval to keep the fabric flat and round. Increase by working 2 single crochets into each corner stitch at both ends. After two to three increase rounds, you should have around 50–54 stitches, and the base should lie flat without puckering or cupping.

Step 4: Work the Sides

Once the base is the desired size, stop increasing and work even — one stitch into every stitch around — to build the walls of the bag. Continue until the sides measure approximately 5–7 centimeters tall, or until the body of the bag reaches the height of your frame opening.

Step 5: Shape the Top Edge

On the final round or two, you may need to decrease slightly to match the shape of your frame. Many frames have a slight curve to the top opening. Compare your crocheted piece to the frame regularly as you work these final rounds, and adjust decreases accordingly.

Step 6: Finish and Block

Fasten off and weave in all ends. Lightly wet-block your finished piece — dampen the fabric, shape it gently, and allow it to dry flat. This evens out the stitches and makes attaching the fabric to the frame much easier.

Step 7: Attach to the Frame

Thread a tapestry needle with a length of matching yarn. Open the frame and hold it against the top edge of the crocheted bag body. Using a whip stitch or overcast stitch, sew the crochet fabric to the holes along the frame’s edge, working evenly from one hinge to the other on each side. Keep your tension consistent so the fabric doesn’t bunch or pull. When both sides are sewn, test the clasp to make sure it opens and closes cleanly.

Stitch Variations Used Across the 18 Samples

Part of the beauty of the 18-sample system is that it introduces you to a variety of surface textures without requiring you to completely rebuild your foundational knowledge. Once you know the base pattern, each new sample is simply a modification.

The moss stitch — alternating single crochet and chain stitches — creates a beautiful grid-like texture that is elegant on smaller bags. The linen stitch, similar in construction, produces a tighter, woven-looking fabric. The half double crochet throughout gives a slightly taller stitch height and a soft drape that many makers prefer for samples meant to carry soft items like lip gloss or earbuds. The shell stitch, when used as a border on the top edge, adds a flared, decorative finish that frames the hardware beautifully. Bobble stitches, used sparingly, create lovely dimensional dots — beautiful as an allover pattern in samples 12 through 15 of the standard collection.

Color Pairing Tips for All 18 Samples

One of the most enjoyable aspects of working through an 18-sample collection is planning the color palette. A few principles make this process easier and more satisfying.

Work in a cohesive palette across the collection if you plan to display or sell the bags together. Choose three to five base colors and two to three accent colors, then rotate them across the samples in different combinations. This creates visual harmony without making every bag look identical. Neutral backgrounds — cream, beige, dusty gray — make almost any accent color pop. Coral, sage green, dusty rose, and terracotta are all popular accent choices that photograph beautifully. If you’re new to color pairing, a simple two-color scheme works wonderfully. Use the main color for the body and the accent color for the final round of the sides and the attachment row. This creates a clean, modern look with very little complexity. For samples where you want more visual interest, consider a variegated yarn for the body paired with a solid accent. The shifting colors in the body create movement and intrigue without requiring you to manage multiple yarn strands.

Troubleshooting Common Problems

Even experienced makers run into small challenges with frame bags. Here are the most frequent issues and how to solve them.

The bag body doesn’t lie flat. This usually means there aren’t enough increases in the base rounds. Frog (unravel) back to the base and add one or two more increase rounds before building the sides.

The fabric bunches when attached to the frame. This happens when the crocheted edge is slightly longer than the frame opening. Before sewing, count the stitches along your top edge and compare them to the number of holes in the frame. You may need to evenly space your stitches or skip a hole here and there to distribute the fabric evenly.

The clasp won’t close cleanly. This usually means the crocheted fabric is too thick at the attachment point. Try switching to a thinner yarn for the final two rows before attachment, or use a backstitch rather than a whip stitch to create a flatter seam.

The bag loses its shape after use. Light stiffening spray on the interior, or a simple fabric liner glued or sewn inside, will significantly improve shape retention.

Finishing Touches and Embellishments

Once your bag is attached to the frame, you can add embellishments to match the specific sample you’re working on. A small crocheted flower stitched to the front panel is perhaps the most popular choice — it’s quick to make, easy to attach, and adds a lovely handmade charm. A tassel made from matching or contrasting yarn, attached to the frame hinge, adds movement and playfulness. A few hand-stitched French knots in a contrasting color add texture without bulk. And if you’re feeling adventurous, surface slip stitches worked across the finished bag body — in a geometric or floral pattern — add extraordinary visual depth.

Final Thoughts

The mini frame bag is one of those rare crochet projects that delivers professional-looking results relatively quickly, teaches you genuinely transferable skills, and produces something you’ll be genuinely proud to use or give away. Working through the full 18-sample pattern collection is a journey — in color, in texture, in technique — that leaves you a more confident and versatile maker by the end.

Start with the simplest variation, get comfortable with the base pattern, and then let yourself experiment. Each of the 18 samples is an invitation to try something slightly new: a different stitch, a bolder color, a delicate embellishment. By the time you’ve worked through them all, you’ll have not just 18 beautiful bags, but 18 small lessons in what crochet can do.

Pick up your hook, choose your first colorway, and start that foundation chain. The satisfying click of a finished frame bag is waiting for you on the other side.
