As it turns out, shortly after I posting asking for help with the quilting I received a phone call that I needed to work there this morning. I wanted to finish the wallhanging and present it today, so last night I rushed thru the quilting and gluing all the 3D motifs in place.
I ended up doing my much-loved feathers but only across the bottom and partway up the sides. I started to cross hatch the rest of the 'sign' background area, but finished the diagonals in one direction and decided I liked it that way! The suggestions for 'simple' were spot on. I would have liked the idea of quilting dogwood blossoms and leaves, but didn't have time to design it that way. I can do feathers without too much thought. ;-)
