Hold the yarn tight enough to keep tension on the yarn but loose enough so that it can slide through your fingers while you crochet. [1] X Research source

Now, there are LOTS of different theories on the best way to weave the yarn through the piece. Some people use a yarn needle, others use the crochet hook, some people weave the thread back and forth through the first and/or second rows, some people pull it in a single line through the middle of the first row. Experiment and find a way that you like but most methods likely work equally well.

If you are new to crocheting, make potholders or scarves that are worked in flat rows. [5] X Research source Then learn to crochet in the round and make granny squares and hats. [6] X Research source
