It's not much a fun fold, but I do get my extra cookies. I pulled out some snowmen inspired by her second teapot image, and coloured them to match the DP which is a very busy pattern and one I was struggling to use up. Wrapped some ribbon and then silver cord around the spine of the card BEFORE sticking it closed, and added some Stickles to the snowmen.
I winged the measurements a bit, so I don't think my panel is exactly square, but it's not off by much.
