I use Steam a SeamLite 2.
You can draw on it and then cut out, take the backing off and stick it down temporarily. You are able to move it around until you get it just right and then iron it down. It's also good to sew through (IME) for quilting. Another thing I like is that I can have my background hanging on my design wall and stick the SaSL2 applique directly to it and it will stay there for me to step back and look at it.
