PolyShrink is a flexible, versatile plastic that shrinks to half of its original size when baked in a conventional oven. When it bakes any pattern applied to the surface is reduced by 50%, intensifying colours and adding crispness and delicacy to the lines. Shrinking also draws most pigments into the surface making them permanent.

In its unbaked form shape with scissors or perforate with an ordinary paper punch. Use coloured pencils, paint, markers or rubber stamps to decorate.
