These are very simple to make. I used metal hoops to crochet around, but you can pretty much use just about anything circular. These are a little small, maybe about 2 1/2" in diameter. I used Omega No.2 Nylon crochet thread (color is grape) that I purchased online from Annies Attic and a 1.65mm crochet hook. I just did a single crochet all the way around the metal hoops until they were covered, I poked a small jump ring through one of the single crochets and into an ear post that I got at my local Joannes Fabric Store, and It was done.
If you've never worked with nylon thread before, something that you might notice is that after fastening off with your finished project, the thread is hard to keep in place and it unravels. Nylon thread has a luxurious sheen and feel to it, and a knot is difficult to keep in place. I've tried just about everything to keep my ends in place, including using beading cement/glue. Take it from me... DO NOT use glue, it leaves an awful smell behind that is hard to get rid of. What I have learned to do is very carefully clip the end of the yarn and use a lighter flame to melt the ends and hold them in place. This seems to work well, but I am by no means an expert in this subject. So if anyone out there can give any helpful suggestions, I'm welcoming you to PLEASE share.
