That looks like a very sophisticated PP project!
The one thing I learned the hard way and will always be sure to do is REGISTRATION MARKS!!! Do not forget to make a lot of colored-pencil marks between segments of the block so when you go to join them all you can line them up perfectly.
The other thing I liked which I picked up at the Judy N class is the use of the glue stick. Works like a charm to keep the fabric in the right place.
Please do post a picture! Love to see it!
