I was sent an email about this challenge, and decided this would be a great idea to use of some of that tall stack of paper. Here is a link to the challenge.
I followed the sketch, but very loosely. I did a side fold card instead of a top fold to start with, and changed the proportions of the two stacked rectangles on the front. I also did not have room next to the stacked rectangles for a sentiment, so will be adding one to the bottom right.
I thought this turned out pretty cute, so I made two of them.
I then decided to change it up just a little, using the same components, but made the design up-side-down. I think this came out pretty cute, too. On these, the sentiment will probably be on the top left, although I'm also considering across the top rectangle at a matching angle.
