Once the pieces are all dry, glue them onto the barrette. You will need to layer them to hide the metal completely. These do have a tendancy to catch in the hair if you leave the pokey bits out, so try to arrange the puzzle pieces so the outer edges are mostly flat. You can also cut out a rectangle or oval from cardboard that will cover the metal and use that as a base for your designs. You can try painting a picture or design onto the base before gluing it to the barrette, or you can use other objects as a decoration.
Some great ideas are fancy napkins, tissue paper, stamps, or stickers.
For napkins and tissue paper, tear them into small bits and paste them to the base, using white school glue. Paint the glue over top of the finished product for a glossy, clear protective finish. You will surely think of other ideas as you work. Look around for interesting items that could be incorporated into a barrette and go nuts. Inc.
