I had never heard of this technique, but I just watched one of the videos. Wow - seems like a huge waste of fabric! I would guess that it would work okay though, but the trick would be starting with the right size center squares and strips. They would not necessarily be the same size for all the components of a block. I will stick with methods that don't throw away so much fabric. (Yes, I know you can supposedly use up those little pieces that you trim off - but I know I would just toss them.)
