I made this tree for a VBS (Vacation Bible School). This tree stands nearly 12 feet tall and is nearly that wide.
I had to make it in a shop that has a ceiling of 8 foot and it had to be transportable.
I started off making about a 7 foot tall frame from 2x4s. I wanted the bottom to curve in some and not be a square tree. So the I cut 45 degree angles on two of the pieces.
