Now as an alternative, you could use duct tape. The bling won’t stick to it, but you could always get several colors of duct tape and let the kids make their own. They make great party decorations, too!
For this table setting I used one painted tube in the center and glued a large flat washer to the bottom to make it stand. The 2 on either side of the purple ones were made using long, thin vases filled with clear stones. I had the Christmas balls just sitting face down on top and it worked great!
