I would start with something with only four pieces to a block. Make a small wallhanging so you ingrain the backwards thinking into your brain. Then go for your Kaleidoscope!! Add a quarter is a huge help. Once you know the size of piece that you need for each section then pre-cut them, stack them up and chain piece a bunch. You will make less mistakes.
My next project is Judy Niemeyer's Bali Wedding Ring. I did her Autumn Splendor and Ive done a Karen Stone also.
