This is a beautiful pattern. I can't find out if there are any fractional stitches in the pattern on any of the other sites I checked. I did find a description of Sandy Orton the designer and it said that she likes specialty stitches in her designs so perhaps there are some in this project. I would say that as long as you are an intermediate stitcher you could do this project. This is definitely not a project for a beginner.
Perhaps someone on this chat room has done this project and can be more specific on their answer. I saw all the different season projects she has designed and they are all beautiful. Good luck.
