Oh, what a great book, sounds like the must have for any sewer from beginner to expert! I want, I want!

I've found using a stabilizer over the seam plus a walking foot works to keep the two different fabrics together, no more pulling, distortion etc. Just a lot of work pinning the stabilizer very frequently all along the seam line. I experimented with the stabilizer between the seams, on the velvet side, or the other fabric - doesn't matter, any works as long as you use a stabilizer.
