Making patterns with trominoes
These heptominoes were in my nightmares for a week
The paper cut sample of the hardest piece I've ever designed. There were so many hours spent on this heptomino puzzle design that I actually started to know all 108 of those evil little pieces!
Making full sized templates for the tetromino piece was using and wasting way too much paper so I started making mini versions until I got the design right ... which just happened to be the perfect size for my little model Tati :-)
