I have the larger size grundeboard set and love them so I decided to buy the mini's for crafting cards, tags, and bookmarks.
They are a perfect size and they are lots of fun to use--I ink them, paint them, and glue on them.
I love this product! Paint it, glitter it, sand it, do your darndest, you can't destroy it, and it looks GREAT!! Add eyelets, ribbon, whatever...It's the most versatile product I have found.
I'm glad I took the plunge and got the grunge! LOL So easy to work with, fun to ink and spray and distress. My only issue is the pieces are really small, and they're a bit of a pain to remove from the sheets. I ripped a letter trying to remove it. And Tim said it wasn't possible - HA! ;)
