I REALLY, REALLY, REALLY liked this fun-with-plywood-shoji-paper
so much so, I ordered some Shoji paper on amazon, and did three so far. One was a turtle stencil my daughter drew, and another was based on a piece of chinese furniture, the third one was found on Etsy by my daughter.
(So reproduction of the later 2 should not be done for sale)
boxes were created on boxes.py
here are the 2 svg files (I removed the japanese wave, based on jules post)
