I hacked up a whole fat quarter yesterday. I discovered for myself that it is really hard to accurately cut one layer of fabric. Then, I got my blocks cut, and then I discovered that I did not have enough for what I wanted to do, I threw the pieces in my scrap basket and went looking for a bigger piece of fabric today.
Success! I found a piece of Kaffe Facett's fabric that I bought a few years ago that is giant paisleys- I hope it comes out OK as I cut it into 31/2" blocks. It is shades of orange, lavender, and greens, with an off-white background. I am putting with it some orange and an off-white print that looks like dried flower petals.
