I made this pin cushion from a Better Homes and Gardens site. The instructions were clear and the project was done in no time. I made a few adjustments to the bottom because I wanted it to be sturdy and flat. Instead of using interfacing, I used a product similar to flexi-firm/Timtex. I suppose you can also use cardboard. I love the colors and I am embarassed to say that I am madly in love with it.
