To prepare the web, spray it on both sides with white enamel paint. Be careful not to hold the can too close, or you might tear the web. Hold a piece of black construction paper under the web. Center the web on the paper and break the main fibers that hold the web in place, allowing the web to fall onto the paper. This print will be nice enough to frame or mount on cardboard.
Family members can have fun making their own buttons for articles of clothing they sew.
Place the dowel between pieces of cardboard to shield it, and put it in a bench clamp or vice. Drill two or three holes into the end of the dowel. Center them so you can use them for the holes in the buttons. If you don't have a drill with a bit, make holes by twisting an awl or leather punch into the wood. Use a hand jigsaw to saw off rounds of the dowel to the thickness you desire for a button.
