Ever so slowly, I've been chipping away at my my vast collection of UFOs. I completed a top consisting of blocks pieced by guild members for the purpose of supplying a quilt for a charity organization's fundraiser.
I added sashing with dark green cornerstones, before finishing the top off with a 3" border. I made the quilt as large as possible with the blocks that had already been pieced, which resulted in a 3 x 4 layout. As an added bonus, this size doesn't need the back to be pieced since it measured shy of 43". If you're hiring a long armer, they prefer more leeway (a back that is 8" larger in width and height that the quilt top), but on a domestic, it should be manageable.
In case you want to make your own, I've put the free pattern up on Craftsy.
