Just the other day I was trying to figure out how to make a wood block puzzle that I saw on Potter Barn Kids' website, and this morning I came across this fabulous post from Emily at Not So Idle Hands
She turns these blocks of wood into a super-cute photo puzzle!
She used photos of her kids for grandparents and such, and I think it would also be cute if you made a puzzle with photos of grandparents (or even yourself!) and gave them to your kids to put together. I can't wait to try this! It's so easy and inexpensive! So hop on over there and get the how-to!
