What you need:
*tin foil what ever size ya like (I reused a clean smallish piece from take-out)
*paint brushes and sponges
*tissue paper scraps
*glitter, sequins, plastic jewels and/or other collagable fun
Give your kidlet a sheet of tinfoil. You can wrap the foil over a piece of recycled cardboard or keep it on a tray or cookie sheet for easy mobility. You will want a sturdy surface underneath when your wee gets all glue happy. With the foil, set out a shallow dish or bowl of tissue paper scraps, either cut or torn. You will also want to set out a small cup of watered-down glue, a paintbrush (a sponge brush works wonders) and some collagable bits.
If you are brave, set out the supplies and let your wee ones have a go. For the not so brave I have broken it down into steps of a sort.
These would make for awesome cards for family and friends. Once dry, glue to the front side of a blank card and cut down to size. Have fun!
