I would take the rhinestone off. I've been using the felt pads that are meant for the bottoms of furniture legs. You can get a pack of 48 of them in the hardware department at Walmart. One side is adhesive, I put that side into the cap. Then, I run hot glue on the felt and attach it to the bow / flower. I've also used 1 inch round wooden discs, and those work well too, but the felt pads are just a little thicker and fill the cap a little better. You can get the wood discs in the wood crafts section at Michael's. HTH!
