I made this for a gift exchange with a gift card for my friends, we are all scrapers and they all loved the card. My only tip is to glue the little flaps on the inside and not the outside. The envelope lays flatter.
This is a very clever little die. I have already made several cards and given them out. It works very well and I love it. It will be one of my favorites from now on. I recommend this to any card makers.
