What can I use instead of a yarn needle?
You can use a crochet hook, for best results, use one one or two sizes smaller than the hook you used to make it. That way it can just slip inbetween the stitches.
What else can I use to crochet hair?
If you don’t have a crochet hook, don’t worry there are two other alternatives that many of you may already have in your home. You have the choice of using a bobby pin or a hair beader. I have used the bobby pin technique and it works great.
