Lace weight can either be 1, 2, or 3ply and knitted or crocheted on 2mm to 3.5mm needles or hook. Used for delicate lace knitting and intricate work, baby garments, and fab for lightweight shawls, gloves and superfine socks. It is advisable to do a 10cm x 10cm square so that the needle size or hook can be adjusted. We all knit and crochet differently, some of us work quiet tightly and others work quiet loosely, so size of needles or hook used is important to achieve correct tension for best results.
