How to Make Romanian Lace Cord
Step 1 Leave a long tail, chain two. Sc in second ch from hook. Rotate piece one-half turn, so the loop at the beginning edge is below your hook. Keep the yarn behind the hook when rotating piece.
Step 2 Insert your hook in the loop below, yarn over and draw up a loop, yarn over and draw through two loops on hook (making a single crochet).
Step 3 Rotate the piece one-half turn, so the two loops at the beginning edge (near the base of the single crochet you just made) are below the hook. These are the two loops of the final yarn over of the second-to-last single crochet you made.
Step 4 Insert hook in both loops, yarn over and draw up a loop, yarn over and draw through 2 loops on hook (making a single crochet). Repeat Step 4 to desired length.
