Here's another awesome idea I found on Pinterest!!!
This is my first attempt. I am waiting on some more filigree ring forms to come in...apparently the ones I purchase from Etsy are being shipping from HONG KONG! These ring forms are from Joann's, I bought all they had in stock this weekend! They are not as decorative as the ones I ordered, but adjustable just the same.
For the base of the ring (on three of them) I used these big wooden buttons that I got from my Pick Your Plum giveaway!! But any larger button would work, like I used on the black ring. I used jewelery glue, E-6000.
