The only thing that's a little tricky is 1/8" seams. I sewed this on my Singer 99 because of the feed dogs on the newer machines. 4 identical repeats, 2 cut the same, the other 2 cut different sew them together and then cut them again and sew together. Best used with a large pattern. This was such light colors wasn't really sure how it would come out but am going to try bright and bold next. Lots of sewing on those little 1" squares.
