Ack, you knit chain mail! That's awesome. I tried my hand at some simple stuff and failed miserably.... I'll just have to stick with knitting yarn! hehe That pony is incrediable, does it stand on it's own because that's what it looks like!
Rings sizes for chainmaille do vary quite a bit depending on weave, wire size, the finished size of the item and the results you are looking for. If you give me more of an idea on what you want to make I may be able to help.
Chainmaille ponies - wow, that's really different! Kudos to you for your skill at this uncommon craft. Hey maybe you could pick up commissions for chain mail ponywear - you know, for people who want to dress their ponies up in renn / medieval garb.
