An envelope and card in one! The Pink Stripe Love Letter is a stationery set that comes with everything you need for 2 letters! Write a lovely message to a special someone on the inside of the heart shaped card then fold it into an envelope and seal
I like this, but for my poster I think it would be a little complicated and would detract too much. Also it would be hard to get my postcards in the space left within the folds. I also like the idea of using a sticker to keep the piece folded.
