Make functional disposable paint brushes with junk you probably have laying around in the garage right now! You can make these REALLY fast and costs basicly nothing.
The other day, one of the kids was wanting to paint his lego man's visor with silver paint. The paint was easy to find, but I was unable to find those disposable brushes. I looked at my rather messy workbench and saw everything I needed to make a brush quick and easy!
