Crochet is a process of creating textiles by using a crochet hook to interlock loops of yarn, thread or strands of other materials.Hooks can be made from a variety of materials, such as mettal, wood, bamboo or even plastic.The key difference between crotchet and knitting , beyond the implements used for their production, is that each stitch is completed before the next one is begun, while knitting keeps many stitches open at a time.Some variant forms of crotchet, such as Tunisian Crochet , do keep multiple crochet stitches open at a time.Crocheters have the ability and range of stitch combinations to create delicate, intricate designs and patterns.
