Old Barn wood  

Have you thought about making yourself a small, wooden box to store your cards, etc. and keep them protected?

I use plastic bins to store my sample crafts or completed projects until they are sold or go with me to a craft fair. Since I have various craft sizes, I use all different sizes and shapes of bins.

I'm not sure quite what it looks like, but it could be like a faux fence, either along the bottom of a wall, or on the wall. Maybe attach something on the wood to make it like message board. I don't have very many good ideas, but it sounds really cool. I hope you have fun deciding what to do with it.

I love the idea of bird houses, those would look great! Or how about a stool, or bench? You could paint the back with a little design of some sort. Or how about shelves? Again, you could put a little accent paint on them to decorate them a bit.

Good luck and have fun!
