This is a creative game made up of small coloured plastic beads that are placed one by one on a pegboard to form a picture or pattern. 
The board acts as a support to keep the beads in place. But you can make whatever shape you want.

Once the pattern is finished, an adult heats the beads with an iron, placing a sheet of baking paper in between. The heat slightly melts the beads, which stick together without losing their shape. After cooling, the pattern becomes solid and can be removed from the board.
