This card isn't for a challenge. My nephew and his wife are new parents to a baby boy so this is the congrats card I made for them. The fold is on the left sleeve so it opens like a regular card. It wasn't until after I was done with it that I realized it would have been a lot easier if I made the fold along the top....not sure what I was thinking. The tiny square buttons are just ones I had in my button jar....pretty good fortune finding 2 tiny white buttons!
