The Jera Brandvig workshop was good, not great. A lot of pushing the books. The only example that we actually worked on was with the top sewn directly onto the batting, plus any extra quilting design wanted on it. Then those blocks were sewn together with a 1/4 inch seam. Then the back is whole cloth, stitch in the ditch.
Her other two methods which we did not do in the class are to join the top blocks with strips, but back is still attached via stitch in the ditch. The other is that both front and back are attached with strips so that the back has a sort of checkerboard look. She didn't show how to do it, rather pushed us to her new book which teaches all three methods (the first book only teaches the first two methods.) So, unfortunately I have no idea how either one with the strips actually works. We thought we were going to be taught all three, so that was kind of disappointing.
