Materials and Preparation

Materials:

• Yarn: Cotton or acrylic yarn in 4–5 complementary colors (e.g., shades of pink/magenta/cream or turquoise/teal/lime/beige) plus a neutral shade (cream/white) for the join and top border.
• Lining Fabric: A small piece of cotton fabric matching your purse dimensions.
• Interfacing/Stabilizer: Non-woven fusible interfacing (flizelin) to give the fabric lining extra structure and firmness.
• Zipper: 1 zipper matching the top length of your purse (approx. 20–25 cm / 8–10 in).
• Optional Accent: Wooden beads and yarn tassel for the zipper pull.

Tools:

• Crochet Hook: 2.5 mm – 3.5 mm (select according to your yarn weight to keep stitches neat and firm).
• Yarn Needle: Tapestry needle with a wide eye for weaving in ends and joining pieces.
• Sewing Needle & Thread: For hand-sewing the lining and zipper (or a sewing machine).
• Scissors & Sewing Pins: For measuring, cutting, and holding fabric in place.

Preparation Notes:

• You should be comfortable with basic crochet techniques including working in the round, double crochet clusters, working in turning rows, and color changing.
• Ensure all yarn ends are neatly woven in as you finish each square and triangle to make final assembly effortless.

Gauge, Approximate Size, and Pattern Notes

Gauge:

Each 4-round granny square measures approximately 7 cm x 7 cm (2.75 in x 2.75 in). Precise gauge is not critical, but consistency across all squares and triangles is essential for seamless assembly.

Finished Size:

Approximately 9.5 in x 5.5 in (24 cm x 14 cm) when laid flat.

Special Techniques:

• Granny Square & Triangle Joining: Joining motifs along the edges using double crochet cluster connection rows to create a continuous fabric.
• Fused Fabric Lining: Applying fusible interfacing to lightweight fabric to prevent sagging under weight.
• Seamless Zipper Installation: Hand-sewing or machine-stitching the zipper directly between the fabric lining and crochet top edge.

Step-by-Step Pattern

Part 1: Classic Granny Square (Make 6)

• Round 1: Start with ch 4, sl st into the 1st ch to form a ring (or use a magic ring). ch 3 (counts as 1 dc), work 2 dc into the ring, ch 2, 3 dc into the ring, ch 2; repeat from * to * 2 more times. Join with sl st to top of starting ch 3. Fasten off color. (4 groups of 3 dc, 4 ch-2 corner spaces)
• Round 2: Join new color in any corner ch-2 space. ch 3, 2 dc, ch 2, 3 dc into the same corner space. ch 1, in next corner space work (3 dc, ch 2, 3 dc); repeat from * to * 2 more times, ch 1, join with sl st to top of starting ch 3. Fasten off color.
• Round 3: Join new color in any corner ch-2 space. ch 3, 2 dc, ch 2, 3 dc into corner space. ch 1, 3 dc in next ch-1 side space, ch 1, (3 dc, ch 2, 3 dc) in next corner space; repeat from * to * around, join with sl st. Fasten off color.
• Round 4: Join new color (or main neutral shade) in any corner space. Repeat the granny square pattern, adding 3 dc clusters into each side ch-1 space and (3 dc, ch 2, 3 dc) in each corner space. Fasten off and weave in ends.

Part 2: Half-Granny Triangle (Make 4)

• Row 1: ch 4, 2 dc in 1st ch (center ring), ch 2, 3 dc in same ch, ch 2, 1 dc in same ch. Fasten off color. Turn.
• Row 2: Join new color in the first 1-dc space at the edge. ch 3, 2 dc in same edge space, ch 1, (3 dc, ch 2, 3 dc) in top corner ch-2 space, ch 1, 3 dc in last edge space, ch 2, 1 dc in same space. Fasten off color. Turn.
• Row 3: Join new color in edge space. ch 3, 2 dc in same space, ch 1, 3 dc in next side ch-1 space, ch 1, (3 dc, ch 2, 3 dc) in top corner space, ch 1, 3 dc in side ch-1 space, ch 1, 3 dc in edge space, ch 2, 1 dc in same space. Fasten off color.
• Row 4: Repeat the triangle building principle to match the number of rounds in your granny squares. Fasten off and weave in ends.

Part 3: Assembly & Top Border

Motif Layout & Joining:

Arranging 6 squares diagonally and filling the top/bottom serrated edges with 4 triangles creates a rectangular pouch shape folded at the base:

1. Arrange the 6 squares point-to-point in a grid layout (3 squares on front panel, 3 squares on back panel, tilted at a 45-degree angle).
2. Place the 4 triangles into the top and bottom V-shaped gaps to square off the top edge and lower corners.
3. Join motifs together on the wrong side or right side using sl st or sc seams using your main neutral yarn color.

Top Edge Border:

Working in continuous rounds along the top opening of the assembled purse:

• Round 1 (Cluster Decreases): Join neutral yarn at top corner. Work groups of 3 dc in each ch-1 side window around the top opening. At side folds and center dip junctions, work 2 dc under one chain space and 2 dc under the next chain space to keep the top edge straight and prevent bulging. Join with sl st.
• Round 2 (Double Crochet Row): ch 2 (counts as 1 dc), work 1 dc into every dc stitch from the previous round across the entire top circumference. Join with sl st.
• Round 3 (Single Crochet Finishing): ch 1, work 1 sc into every stitch around for a firm, clean top edge. Join with sl st, fasten off, and weave in all remaining ends.

Part 4: Lining, Zipper & Finishing

1. Cutting Fabric: Fold your lining fabric in half. Lay the crocheted pouch on top and trace around the outer edge. Cut the fabric leaving a 1 cm (0.4 in) seam allowance on the sides and 1–2 cm (0.4–0.8 in) at the top.
2. Interfacing: Iron fusible interfacing (flizelin) onto the wrong side of the fabric pieces for structural support.
3. Attaching Zipper:
   • Place zipper face down along the top edge of the right side of the fabric lining.
   • Sew along the zipper tape edge (by machine or hand with small backstitches).
   • Repeat for the second top edge of the fabric lining on the other zipper side.
4. Side Seams: Unzip the zipper halfway. Fold lining right sides together and stitch down both side seams.
5. Attaching Lining to Crochet Pouch:
   • Insert the sewn fabric lining inside the crocheted body.
   • Pin the top edge of the lining (just below the zipper teeth) to the inner side of the top single crochet border.
   • Hand-sew around the top perimeter using neat, hidden blind stitches.
6. Zipper Pull Accent (Optional): Thread wooden beads onto a handmade yarn tassel and tie securely to the zipper slider loop.

Detailed Pattern Breakdown

1. Granny Square & Triangle Geometry Breakdown:

The purse uses classic 3-dc granny cluster logic, but with an intelligent layout variation:

• Square Motifs: Starting from a central ch-4 ring, each round expands outwards by adding 3 dc clusters into side spaces and double clusters (3 dc, ch 2, 3 dc) into 90-degree corners.
• Triangle Motifs: Function as exact half-squares. Instead of working in a full circle, you work back and forth in rows, turning at the end of each row. The top peak acts as a 90-degree corner, while the base line stays flat by ending each row with a single dc separated by ch 2.

2. Layout Puzzle & Seam Assembly Breakdown:

• Diagonal Alignment: Rather than aligning squares straight horizontally, the 6 squares are turned 45 degrees into diamonds. This diagonal layout creates built-in envelope-style triangular points on the sides and bottom fold.
• Gaps Filling: The 4 half-granny triangles fit precisely into the V-shaped notches at the top opening and bottom corners, turning a jagged motif assembly into a flat top edge suitable for a zipper.

3. Edge Stabilization & Professional Lining Breakdown:

• Contouring the Opening (Round 1 Decrease): Where two motifs meet at a valley or seam, standard 3-dc clusters would create unwanted ruffling. By dropping from 3 dc to 2 dc worked across adjacent spaces, the stitch count is reduced just enough to pull the opening into a flat, straight line.
• Structured Interior: Crochet fabric is naturally stretchy. Adding fusible interfacing to cotton lining ensures that heavy items inside the purse (like lipsticks, coins, or keys) won’t stretch or deform the bottom stitches.

Pattern Questions & Answers

Question: Why does the top opening of my granny square purse flare out instead of lying flat before sewing the zipper?

Answer: Flaring happens when too many stitches are worked across the valleys where the squares and triangles join. On Round 1 of your top border, make sure to reduce stitch bulk across every junction by working 2 dc under one chain space and 2 dc under the next chain space instead of full 3-dc clusters. This slight decrease draws the top circumference inward into a neat, straight edge.

Question: How can I make sure my zipper doesn’t catch on the yarn when opening and closing the purse?

Answer: Position your lining so that the zipper tape sits slightly elevated above the fabric, while keeping the crocheted sc border roughly 2–3 mm below the zipper teeth. When hand-sewing the lining to the crochet edge, make sure your stitches anchor firmly into the base of the sc row rather than loose loops, ensuring the crocheted yarn stays pulled back away from the zipper teeth.

Question: Can I make this purse larger without changing the number of motifs?

Answer: Yes! You can easily scale up the size by adding 1 or 2 extra rounds to each granny square and half-granny triangle using the established pattern logic (3 dc in each side space, 3 dc, ch 2, 3 dc in corners). Just ensure that all 6 squares and 4 triangles have the exact same total number of rounds so their edges line up perfectly during assembly!
