When the picture is completed, the material is stretched over the picture, folded under and the edges taped to the back so that the material covering the picture stays in place. Then the toweling s gently pressed with the finger tips to mold it to the shapes below. To enjoy the picture, feel it through the material. For a visual affect, do a crayon rubbing on the material. This will not interfere with tactual enjoyment of the picture and will add visual interest.
Some combinations are much less pleasant to handle than others.
Shredded paper toweling mixed with starch makes a papier-mache that is minimally messy and fairly nice to handle. Papier-mache can be used any time you want to build up contours or relief on a surface. Use it to build up facial structure on masks, make relief maps or relief pictures. Paper towels torn up into small pieces. Add enough starch to get all the paper wet.
