Floating Cubes has had a long slow development. The cube-top fabric came first - bought at a quilt show in Sydney, perhaps 2006. I knew I would use it for some variation of Stack'n'Whack but I didn't want to just make blocks & a border with it.
Then, I read Quilts of Illusion (again) and saw a most amazing variation of the classic Tumbling Blocks pattern. Immediately I knew I would use the interesting blocks from the special print as the "top" of cubes. I made dozens of these, and enjoyed the process of selecting complementary colours from the scraps stash.
