Roly great work on both the Signs and the boxes. The combinations are virtually endless for the boxes. When they first were introduced back in 2009 folks were making them large, small and one person actually made one that a penny would have trouble fitting into. Besides being extremely easy to make they do not take a lot of time and you can use up your scrap making them. Where I live they sell pretty well right before Christmas and during College graduation season. You might wish to make a different shape keys, a club, a diamond, a spade, a heart, an initial, the choices are limited only by your skill at cutting. You are doing a great job thanks for sharing these with us.
