Cut soda pop can open carefully. Lay it flat and place a stack of books over
it until the aluminum flattens out. Find a picture you would like to emboss onto
aluminum. A good source is stamping books.
After the can has flattened, cut into any shape desired. To keep the edges from
being sharp, cut all designs, such as star points, on a curve. Use a ball point
pen to do outlines on the plain, inside part of the flattened can.
