Remember PosePrints? They have customizable invitations and stationary with a twist — you can choose your background, make up a model from scratch by picking skintone, hair, eyes, clothes, and accessories, and fill in with any text you want! They were fabulous a year ago and they are even better now, with more customization options and nifty ideas. Here's a mockup of a possible invite:
Go play with the customizer, it's fun! And right now you can get 15% off everything with the code "happy1year". Happy Birthday PosePrints!
