When it comes to 2x4's and 1x4's the possibilities are endless.
Here is a fun project that I made with a 1x4, that you can get from any local building supply store.
If you have kids you need a growth chart and if you are like us you have moved quit a few times so it is nice to have a portable one that you can take with you.

2nd~ Paint it.
3rd~ Add your vinyl
