Love the Abby Road Kass! Amazing!
For applique it depends on the project. I either do the fusible,(which I used for the VW) the way Kass does it,(but with freezer paper so no glue needed) needle-turn, or the Lori Holt way with a stabilizer to turn.
Moonworks you're going to have to finish your quilt so everyone can see. It's going to be amazing. Very creative!
