Sizing and Customization

Measure the widest part of your body (hips or chest) and add 2-4 inches (for a snug or looser fit, respectively).
Divide this measurement by two (front and back pieces are equal in width).
Adjust starting foundation stitch count to match this measurement, ensuring the foundation is divisible by 16 for the wave pattern.

Special Techniques

Foundation Half Double Crochet (Fhdc):
- Chain 2, insert the hook into the bottom bump of the first chain, and pull through (3 loops on the hook).
- Yarn over and pull through the first loop only (creates the "chain").
- Yarn over again and pull through all three loops (creates the hdc stitch).
- Repeat in the bottom of the previous stitch.
- Creates a stretchy and neat foundation row.
Back Loop Only (BLO):
- Insert the hook into the back loop of the stitch (leaving the front loop unworked).
- Used for ribbing and cuffs to create texture and stretch.
Decreases (sc2tog):
- Insert the hook into the first stitch, pull up a loop.
