Just finished my top. If you go systematically through the pattern book, you'll be fine. I didn't cut out all the sky squares at the beginning (you need over 500 1.5" squares), but I did cut quite a few which helped me get a jump on it. The instructions suggest pressing seams open which I didn't do. It turned out OK. Some of the blocks are a little tricky to put together - I made my own paper piecing and applique patterns for them. All in all, it was incredibly fun to make. Involving and interesting. Now I need to quilt it but I'm working on a few easier things first. BTW, there's a Jen Kingwell Facebook group, and on this Quilting Board, there's a Kingwell subgroup under "Challenges".
