Make 2 strips
Set hairpin lace fork to 3 in (8 cm) wide. Cast on 189 (231) loops on each fork tine, using the size G (4.0 mm) crochet hook to make the center sc. Fasten off. Thread a length of contrasting yarn through the loops on one side and up the loops on the other side before removing the strip from the fork. Remove the strip from the fork.
Row 1 (RS): using the size H (5.0 mm) hook, insert hook from front to back through 3 loops and make a sc. Sc in same sp, ch 2, * work a sc into the next 3 loops, ch 2. Rep from * across to last 3 loops, work 2 sc into last 3 loops.
Row 2: ch 4 (counts as dc + ch 1), turn, dc in the next sc, sk next 2 chs, * [dc, ch 1, dc] in the next sc (V-st made), sk the next 2 chs. Rep from * across to the last 2 sc, dc in the next sc, ch 1, dc in the last sc.
Row 3: ch 4 (counts as dc + ch 1), turn, dc in the 1st ch 1 sp, *sk the next 2 dc, [dc, ch 1, dc] in the next ch 1 sp. Rep from * across to the last V-st, sk the next 2 dc, dc in the ch 1 sp, ch 1, dc in 3rd ch of the tch. Fasten off.
Rep rows 1 – 3 on the opp side of the strip. Rep all of the instructions for the second strip.
Joining strips: Align strips so the sts are evenly matched and the RS are facing. With a size H hook, attach the yarn with a sl st in the 1st ch 1 sp of the V-st, ch 2, sl st in 1st V-st of the second strip. *Ch 2, sl st in next V-st of the first strip, ch 2, sl st in next V-st of the second strip. Rep from * across. Fasten off.
Fold the wrap in half so the row ends meet. Give one side a half twist, so the bottom row now meets the top row. Using the mattress stitch, sew the seam, working through the row end stitches. Carry the yarn through the hairpin loops loosely as you work. Fasten off and weave in all ends.
