They are both made from the same pattern, but when squaring the bottom corners I cut off more on the red one to give it a smaller squashier look.

Both are a bit wonky, which is slightly annoying. I've got the hang of the glueing now, but it is still a bit fiddly. All in all a great little gift project, and I've cut the pattern onto cardboard now so I can cut all the bits out nice and easily with my rotary cutter when I make one of these again.
