I have seen these boxes everywhere. There are several tutorials out on Youtube and other blogs. I don't remember exactly which one I used for the larger of my boxes but the small box tutorial can be found HERE. I made the small box as a wedding favor sample. The larger one was made first, as a test run. I used a stack of 12"x12"designer paper that someone gave me. It was very thick, great for boxes.
Until next time....Buzzz you later,
