Another topological crochet project, with Shiying Dong’s topological crochet method. (Got a couple requests to link a pattern for my previous post of one of her designs, but https://www.youtube.com/@epimono is all I’ve got! It doesn’t have the four interlocking triangles/circles but it does have this saddle trefoil knot design.)
first feather print modular!
four intersecting triangles designed by robert lang and instructions here

comparison between the crochet version and the origami version!

Bain reversible cable scarf designed by Lucy Hague
I love this pattern! I spent almost two years on this scarf on and off, and I started/restarted it a few times before that. This was one of the first patterns I ever purchased, way back when, and at the time it was beyond my skill level.
