A diagram to knit a skew entrelac cube with 30 squares, 5 per face. Well, I call it a skew cube because the squares that make up the face are at an angle to the face itself.
I haven't knit this cube with this method yet, so don't quote me. I did figure out how to knit it from a model I made, so I'm pretty confident that it's knittable. The nice thing about starting the cube from an edge is that you can make pretty stripes on the cube by following the colors on the diagram. I'll show you later.
