I have been playing with entrelac cubes again. Well, still. This series of diagrams shows what happens when you modify the edges of the squares that form the faces of a cube. The first variation I tried was the hound's-tooth check motif, but there are others now, including the Greek cross and this motif made of 8 squares. The flexibility of knitting lends itself to many such variations. Click through to the Flickr page to see more.
