Even though this one is small I think it is still a nice project that you could make for this summers craft shows. If you have the right sanding equipment you can knock these out pretty quick so I think you could make a profit from these. If you have to hand sand you might have a little too much time in the project for it to be a profit maker. They would make great gifts regardless of how you make them.
The pattern book shows complete instructions but you will see that they are easy to make. Give this one a try and I think you will be hooked on this technique.
