Shumai Bag Crochet Text Study Guide

This project creates a unique "Shumai" (dumpling) shaped bag by combining traditional granny squares with triangular panels, finished with a lining, drawstring, and a durable "shrimp braid" strap.

1. Component Overview

To complete the bag, you will need to crochet the following pieces:

• 1 Large Granny Square: Forms the bottom of the bag.
• 4 Small Squares: Form the lower sides of the bag.
• 4 Triangle Pieces: Form the upper "pleated" section of the bag.
• Accessories: One lining with eyelets, a drawstring with tassels, and two round rings for the strap.

2. Step-by-Step Construction

Phase 1: The Triangle Pieces (Make 4)

• Round 1: Start with a Magic Ring. Crochet 3 chains (counts as first stitch) and 6 double crochets (dc) into the ring.
• Round 2: Flip the piece to work from the wrong side. Crochet 2 dc into each space between the columns of the previous round.
• Round 3 (Color Change): Use a new color. Crochet sets of 3 dc in the side spaces. At the vertex (the top point), crochet 3 dc, 1 chain, and 3 dc in the same hole to create the point.
• Round 4: Follow the same pattern as Round 3 to expand the triangle.

Phase 2: The Granny Squares (Small & Large)

• Small Squares (Make 4): Start with a magic ring and 11 dc. In subsequent rounds, create corners by crocheting 3 dc + 1 chain + 3 dc in the same space. Continue for 4 rounds.
• Large Square (Make 1): Follow the same method as the small square, but continue for more rounds (as specified in the pattern) until it reaches the required base size.

3. Assembly and Joining

• Connecting the Base: Place the right sides of the large square and small squares together. Use single crochets (sc) to join them, matching the stitches one-by-one.
• Connecting Triangles: Attach the triangle pieces to the top of the small squares using single crochets on the wrong side.
• Finishing the Body: Once all pieces are joined, turn the bag right-side out and shape it.

4. Final Touches & Accessories

The Top Border

• Crochet 3 rounds of single crochet around the top edge of the bag.
• Rounds 2 and 3 should have a total of 76 stitches each to ensure a consistent opening.

Drawstring and Tassels

• Drawstring: Take about 236 inches of yarn, fold it in half, and crochet a chain-like cord.
• Tassels: Wrap yarn around four fingers about 7 times, tie it to the ends of the drawstring, and trim to create the tassel shape.

Lining and Shoulder Strap

• Lining: Place the lining inside and align its eyelets with the center holes of the bag. Hand-sew the edges to the bag's interior, ensuring the drawstring remains functional.
• Shrimp Braid Strap: Use two strands of yarn to crochet a thick, sturdy "shrimp braid." Attach it to the bag using round buckles or rings.

💡 Expert Tips

• Flattening: If your finished squares or triangles are uneven, place them under a heavy object for 2 to 3 days to flatten them before assembly.
• Concealing Ends: Always place your yarn tails over the hook while crocheting the next stitches to hide them as you go.
