As luck would have it, my calculations worked. Here is the box. Now this particular creation went to a friend for her birthday. I filled the box with Jelly Belly's and a 3X3 card, but I hope to have a formal tutorial for you soon.
Here is the completed project. I used my new favorite DSP, Island Floral and the Island Floral Die the decorate the top. Now, I gotta run we are off to the Rodeo Parade! Can't miss it. The girls love horses and all those fancy cowgirls that ride standing up and do tricks. Boy, I hope they don't want to do that when they get older!!!
