I took my niece to a small but nice bead show a couple weeks ago. We shopped and brought home a few treasures.
The one item I knew I wanted to get was rubber O-rings. Here's why I needed them.
The added bonus is it builds a more 3-D look into the flowers! I purchased many colors of O-rings, to coordinate (or contrast) with the flower colors.
The O-rings are from My Elements. They have an etsy shop.
