Here are a few of the buttons I've found
(Will update my post when I attach the backs)
My favorite is above, these go with all my denim (and I love the little spiney paisley shapes).
Dressier Pair (will also update this picture when I attach the findings)
Here's a little casual pair, such great tiny details.
Love these buttons! There are findings on the back of these, but this pair is a little larger.
