Round 2: Attach Color B in any ch-2 space. Ch 3, (2 dc, ch 2, 3 dc) in same space, ch 1, (3 dc, ch 2, 3 dc) in next ch-2 space; repeat from * to * around. Ch 1, join with sl st. Fasten off or change color.

Round 4: (Optional for larger squares) Continue in pattern, working (3 dc, ch 2, 3 dc) in corners and 3 dc in each ch-1 space along sides.

Note: We will make 13 squares of 4 rounds each. Feel free to mix and match colors for a patchwork look.

Section 2: Blocking the Squares

Blocking your squares ensures uniform size and helps with even assembly.

To Block:

Pin each square to a blocking board or foam pad to 6″ x 6″.
Spray lightly with water or steam block with an iron held a few inches above.
Allow to dry completely.

Section 3: Arranging and Joining Squares

Suggested Layout:

3 squares for the front
3 squares for the back
2 squares for each side (4 total)
1 square for the bottom

Joining Method (Whip Stitch or Slip Stitch Join):

Whip Stitch: Place two squares right sides together. Using yarn needle and matching yarn, whip stitch through both loops of each stitch across.

Slip Stitch Join: Hold squares with right sides facing up, working through back loops only, sl st across to join.

Join the squares as follows:

First join 3 front squares in a row.
Repeat for back.
Join 2 side squares vertically.
Attach bottom square to front, back, and side strips.
Seam the sides and bottom together, forming a 3D box.

Section 4: Adding the Handles

Option 1: Crocheted Straps:

Strap Pattern:

Ch 9.
Row 1: Sc in second ch from hook and across (8 sc). Ch 1, turn.
Repeat until strap measures 20-24 inches (adjust to desired length).

Sew ends securely to top edge of the bag.

Option 2: Purchased Handles:

Use D-rings and leather straps.

Section 5: Lining (Optional but Recommended)

Lining your bag gives it a polished finish and prevents stretching.

To Add Lining:

Cut fabric to match bag dimensions plus 0.5″ seam allowance.

Insert into bag and hand-sew around the top edge.

Add a magnetic snap or zipper before sewing in the lining if desired.

Section 6: Finishing Touches

Add embellishments like tassels, buttons, or fringe.
Use a steam iron to gently shape the final bag if needed.

Customization Ideas:

Make a flap with a button for closure.
Add interior pockets to the lining.
