The first thing I did was cut my pieces of wood. I used a 1 x 4 that was in nice shape so it didn't require much sanding. I started by determining the length of the tallest snowman, then I adjusted the other sizes by about 2 inches each. I just did the measurements visually, so I don't know what they were exactly, but I believe the tallest one was about 18-20 inches. That's about as tall as you can go using only one hinge like I did.
