You can make your own "Bling Thing" tool cheap...
First, you need some polymer clay, a stiff like tool; such as, a paint brush, paper piercer, or embossing tool.
Second, take a blob of the polymer clay about the size of a large pea and stick it on the end of your tool. If it is warm out let it set for a minute so it don't pop off.
Third, using your tool pick up an embellishment, rhinestone or jewel using the polymer clay end and pop it onto the adhesive you have on your paper. The polymer clay has just enough stick to let go that way your not messing around with tweezers or trying to hold them in your fingers.
