Similar to tatting, but using a needle instead of a tatting shuttle. The difference being with needle tatting is you can use a variety of fibers. Each needle is sized for various fibers.

Use the #7-0 fine needle for crochet cotton sizes 50, 40, 30, and 20 as well as pearl cottong sizes 12 and 8. Use the #5-0 for crochet cotton size 20 and 10 as well as pearl cotton size 5. Use the #3-0 for pearl cotton size 3 and smaller sport and baby weight yarns (size 3 weight, 2 weight, and 1 lace weight). Imported.
