I used to work for an architectural firm - and they always were throwing samples and such away - drove me crazy!! I have a very large box of color samples that I don't know what to do with. They've been sitting in a closet for 2 years now... I really don't want to junk them... they are hard, I believe they are originally used for countertops and such... all one color... some of them actually have the name of the color on the front - so that would need to covered up... my first thought is - key tags or something like that. They are about 2-4 inches long and about 2" wide..
