When you first start to crochet you will need a size H hook and also preferably medium size color acrylic yarn. These supplies are easy to purchase. Left handed people can crochet with their right hand as well as right handed people can. Performing the basics of crocheting involve starting off by making a crocheting loop. With this loop made the crochet hook is inserted into the loop and, then there can be other loops made from this start. If you do mess up with crocheting you can simply undo the mistake without cutting at all. All you would have to do is pull on the yarn loops to undo them. You will make errors but you learn every time you try.
