I have done the goose track, feathered star and am working on the mystery quilt. They are large project. 6 months to a year. I did them as BOM and had to do 10-16 blocks each month. There are a few design oops in each project. They are generous with their fabric requirements. Doing the back the way they suggest is a lot of work, I just put a back and SITD. The each of the blocks take on an average of 40 min to stitch out. For a queen size feathered star or the new Jacobean plan on about $400 for materials and $150+ for the design. I have posted my feather star quilt on the board.
