The longer sew sampler box is perfect for this.

Spent last night cutting fabric using those templates. I love how they don't slip! I have a huge pile of the "A" template cut out. I did make the dividers and the box is all set up to accept fabric. I cut all night while watching television, so my wrist is sore today. Think I'll take a break from cutting and play with some fabric! But, I love those templates!
