I use an open toe foot so I can see exactly where my needle is falling, and with the blanket stitch I dont usually use a stabalizer. With satin stitch it is a MUST!!!! The only concern I would have with appliqueing after it is sandwiched is if you have alot of detail to go around, you would have all that extra bulk to contend with. I think just learning you might want to do it before you sandwich.
