Organize scrap fabric into color groups.
Print out the template drawing onto the double-sided adhesive paper.
Remove the backing from the template drawing and adhere it to the foam block.
Use an Xacto knife to cut into the foam and then for a section of the drawing. Be sure to cut about 1/4 of an inch deep.
Remove the top paper part of the section, leaving the adhesive on the foam.
Use the cut out paper section as a guide to cut out fabric slightly larger.
Take the cut out fabric and place it on the area where you've removed the paper.
Press lightly and then use the back side of a seam ripper or a thin metal nail file to punch the fabric into the foam where it was cut.
Continue cutting out sections, using them to cut fabric, then placing the fabric onto the drawing, punching in the edges until you completely cover the foam block.
Cut thin sections of more adhesive sheeting to place on the sides and press the excess fabric to finish the edges.
Frame or display the art as you wish.
