Here is the challenge fabric I am working with for my beach scene. I have decide to attach most of the people and trees to wool felt with free motion zigzag and invisible thread. I had never quilted through wool felt before. It is wonderful. I put all my wool felt in the washer in hot water squeezed out a lot of the dye, drained the washer and washed all but the cream in a hot wash on gentle. Then threw them in the dryer. The felt comes out all bubbly, but Irons perfect. I think I'm hooked.
