Glue Dots are the Best!!!!
I call these my multi-purpose Glue Dots!! I use them on the back of matted photos, dies cuts, and light weight embellishments. I love them. They are easy to use (just touch the adhesive to the part of the embellishment or matte photo that you want to place it) and have a very strong bond (pages that I made 4 years ago still have everything in place)! I buy Glue Dots Brand whenever I can so that I know that I'll have a supply on hand.
