I decided to take Laure's suggestion of checking out the quilting stencils and chose a couple that I thought might work in the borders of Fall Frolic. I am still slowly quilting my way around the appliqué in that center block, but once I finish doing that, I'll see if one of the ones I ordered will work (and even if they won't work in this quilt, they might work in a different quilt). I am still debating about the crosshatching in the appliqué blocks, because it might be too much and unbalance the quilting that I'll be doing in the borders and sashing.
I'll update you as soon as I decide! Thanks for your comments!!
