That Simple Unit (TSU)
A modular unit from which you can assemble anything you want. Courtesy of Charles Esseltine. I gave some examples of what you can assemble with the TSU, but there is really no limit of what you can do with it.
I made a total of 16 modules, you can assemble in any way you like from 3 modules to infinity. I’d recommend 4 or 5 units for starters. You can find some examples from Anniefolds website.
Paper to use
You need square papers to make this one, in the video I used 10cm wide paper.
