While browsing an origami forum I frequent, I came across a modular that I had not tried, based on 120 degree units:

I have a stack of oddments (the ends cut off A4 sheets when squaring them up) and decided to see if they were close enough to the right size for this module (it called for 2 1/5 x 1 rectangles, my odments are more 2.5×1)

Turns out, apart from being a little loose fitting, that size works fine

The result is a lovely brain bending modular that took me 4 unsuccessful attempts before I finally worked out the weave. It took little time, the result is lovely and I must now search for another procrastigami project to distract me from my marking.
