Scissors, single-hole punch, Colorations Foam Door Hangers, shoe laces, string, or ribbon
Use this shape sheet as a pattern. (The sizes may need to be adjusted.) Trace each shape onto a different piece of foam, and use the scissors to cut them out, and use the hole punch to punch out the lacing holes. (Save the scraps of foam to use with another DIY project that I will be posting about soon.)
If you are using string or ribbon, wrap a piece of tape around each end. Now it's time to start lacing!
