I haven't tried the fusible backing yet, but one of my on-line friends has been a convert since it first came out. Loves it, raves about it.
I do have a project I'm thinking about using it, some hand cross-stitched blocks from a kit I picked up at the thrift store. Colors are definitely 70s, not sure if the stamped fabric was 60s or 70s, but it is not great quality. I'm thinking of doing a quilt as you go, fusing to the blocks and then wide pieced sashing. Blocks finish something like 16", I think I designed the sashing at 4"... I should pull that box off the top of the shelves and start thinking of that sashing as a "quick little project" instead of dealing with the squares first.
