Although I haven't seen this, from the pictures and video, I don't think I would use it. I just don't care for the fabric. I looked online and found it on sale for $5.40/yard - so not inexpensive, either.
If I were doing QAYG, I'd work on figuring out how to make this type of prepared sashing with fabric I have on hand that would work with the quilt. I've never done QAYG, though, so won't be worrying about working it out.
