I did this one round robin style, adding different borders. In places where the math didn't work quite right, I did a plain strip of fabric to get it up to size, the black one that is around the center panel, the leaf one that is around the pieced trees and the fish print and fishing lure print that are in between the LC blocks and the fish blocks. You can easily adapt common blocks to fit your panel or adapt your panel to fit an evenly divisible number that fits your block size. You can even expand to drafting your own. That is what I did with my tree blocks in this quilt. They were paper pieced so once I drew my pattern, all I had to was copy it for the PP.
