I love to crochet afghans. I made quite a few since I was about 19 years old after my mother-in-law taught me. I’m not an expert, but I enjoy it occasionally and make a few items that I proudly gift.
Crochet is an old craft however not as old as knitting. Crochet derives from the French word ‘crochet’ and means “hook.” How appropriate! There are two main types of crochet. One is ordinary or regular crochet, and the other is Tunisian or Afghan crochet.
Materials and Equipment for Crochet
Crochet hooks and yarn, thread or floss are the common materials that are used to crochet. There are so many uses for crochet that the material used to crochet depends on the purpose.
Clothing, edgings (particularly on linen), as well as household furnishings, are very attractive. We crochet rugs and mats with wool or cut strips of fabric, and we use plastic or cording for shopping bags. The material chosen depends on the utilization of the final product.
There are two types of crochet hooks – an ordinary hook is for regular crochet. An elongated hook that looks like a longer regular hook has a stopper on the end. It is called an Afghan hook.
