I had a bit of free time this week so have put together some diagrams for some different colourways for the interlinked tetrahedra shape!
There are step-by-step diagrams for the silver-yellow-green, yellow-orange-red, silver-blue-purple and green-yellow-silver-blue-purple colourways. The pdf is available here: Interlinked Tetrahedra Additional Colourway Diagrams.
They match the steps in the original 3- or 5-colour instructions, which you can find here.
Happy beading!
