I just picked this project up again after a few months off--it's a straight-up applique of the Alabama Chanin "Anna's Garden" stencil. I'm doing it on the bodice pieces of a bolero.
I'm tracing the shapes very lightly on the back with a pen--not a Sharpie, which would bleed too much--and also tracing the spot where they go, very lightly. It's a little tedious and it overworks the weakest part of my brain (spatial orientation). But it's so tidy when it's done.
