The use of the clear plastic is a great help. I was wondering what your back looked like. Will the quilting show on there? If so, what secondary quilting pattern can you do to compliment the feathered wreaths you have done? Are you using a purple thread on your feathers or is that the marking?
I like the stencil ideas that QuiltnNan suggested. If you center the point in the center of the block and they would make kind of a frame around your wreaths.
