Paper. That you sew. Am I the only person who thinks that's super cool? Okay, maybe I am. I first ran across this idea in Hobby Lobby, I think. They sell several empty containers which are perfect for personalizing. I wanted to try the embroidery paper for awhile and finally decided to take the plunge with my cousin's baptism. I love how it turned out! Cute and functional...she's sent along good reports as well.
