You need them for journaling. I got this idea for a stamp from Nastasa at Treasure Books. https://youtube.com/c/TreasureBooks
I was cutting flaps off boxes to cover for storage, (I got lots over Christmas!) and decided to see if I could use Natasa’s idea. I fell the day after Christmas and skinned myself up pretty good. Skinning cardboard was no problem! It didn’t even hurt!
