Square Motif (Make 13)
Foundation: With Color A, ch 4, join with sl st to first ch to form a ring.
Round 1 (RS): Ch 3 (counts as first dc here and throughout), work 2 dc into the ring, ch 2. (3 dc into ring, ch 2) 3 times. Join with sl st to top of beg ch-3. Fasten off Color A. [12 dc, 4 ch-2 spaces]
Round 2: Join Color B in any ch-2 corner space. Ch 3, (2 dc, ch 2, 3 dc) in same ch-2 space. *Ch 1, skip next 3 dc, (3 dc, ch 2, 3 dc) in next ch-2 space; rep from * twice more. Ch 1, skip last 3 dc, join with sl st to top of beg ch-3. Fasten off Color B. [24 dc, 4 ch-1 spaces, 4 ch-2 spaces]

Ch 3, (2 dc, ch 2, 3 dc) in same ch-2 space. *Ch 1, (3 dc in next ch-1 space, ch 1), (3 dc, ch 2, 3 dc) in next ch-2 corner space; rep from * around, ending with ch 1, 3 dc in last ch-1 space, ch 1, join with sl st to top of beg ch-3. Fasten off yarn and weave in ends. [36 dc, 8 ch-1 spaces, 4 ch-2 spaces]
Assembly & Finishing Touches
Lay your 13 finished squares out in a flat T-shape or cross layout to plan your final bag construction. Fold the outer squares upward to form the 3D body of your bag around the central base square.
Use your tapestry needle and a whipstitch or flat slip stitch join from the wrong side (WS) to seam the adjacent edges securely together. Double-check all stress points around the base and corners to ensure maximum durability.
Weave in all remaining yarn tails securely using your tapestry needle. If desired, hand-block your assembled bag lightly with steam or water spray to crisp up the square motifs before attaching any optional straps or fabric lining.
Pro Tips for Flawless Results
- Maintain a consistent hook size and hand tension across all 13 squares so they align perfectly during the seaming process.
- Weave in your yarn tails as you finish each individual square to save yourself hours of tedious finishing work at the very end.
- Opt for a sturdy plant fiber like cotton or a cotton blend to prevent your finished bag from stretching out of shape when loaded with everyday items.
