My son has carved a stamp using the rubber carving medium and a pair
of point nose short blade scissors he just snipped away the material
no in the picture. It was a letter I also suggest other basic
designs, snowman, dog house,anything simple you can just snip away
the excess. I also tried out a tweek method using tweezers to pinch
out bits of rubber from the outer shape , this seems to work pretty
well too. Good luck Carol
