I made this one yesterday to go with my large makeup bag. This one is going to hold all of my lipglosses, chapsticks, travel powder, etc that I keep in my purse. I made this one 5x5x5, a perfect cube. The large one (I forgot to mention) is 5" wide x 8.5" long x 4.75" high.
P.S. I do want to brag and say that I didn't use a pattern for either one of these ;). Since they were just rectangles it was pretty easy to do the math to figure out the dimensions of the blocks (with seam allowances).
