Little person cards
When LP was born last year, I made a few (ahem a lot) of thank you cards for the generous and thoughtful friends and family that gave us gifts for her. Each card was different and used up quite a few of my ribbon and envelop stash. It didn't get anywhere near the end of my button stash though!
The cards were trifolds with photos of my LP in the middle fold. Rather pleased with how they all turned out - but they were most impressive in bulk!
