In 45 years of crocheting I had never tried broomstick lace crochet! Watched this tutorial and this tutorial and decided to try a practice piece with 20 sts, using size I/9 (5.5 mm) hook for the crochet and size S hook for the ‘broomstick’. Worked the piece to scarf length, then added an open shell border all around. In this fine-weight yarn, the scarf is light as air. Interesting and fun to work!
