Love, love your quilt. Eagles look fabulous on the backdrop. Lots of great ideas here. It all depends on your skill level of quilting. Perhaps you can draw out your quilting design ideas on a sheet of clear plastic placed over your quilt to see what you think would be best. I have bought clear plastic on a roll from Walmart/hardware stores. It comes in different thickness' and you can wash off if you use the dry eraser markers. Very helpful when you can't decide which design would work. Good Luck and please post when quilted.
