thats pretty!

bit large for my tastes, looks by the hang, my guess is 3/8 inch ID.

care not to hit it with something, you will rip it, copper is quite soft.

I highly recommend www.theringlord.com thats where I get my supplies from. great prices, great quality, really fast service.

I like the galvy strip you have in it. and I like the hang of your expanding circle.

congrats!
