First I used sashings without corner stones and used 1/2 finished sashings in between and to frame it. See next photo to see the spool of thread cornerstone. I purposely created a wide enough sashing to incorporate the patchwork spool of thread. I like to FMQ and will design sewing themed motifs from Lori Kennedy. In Barb's class, she shows how to line up corner stones and sashings which was very helpful, I learned a lot. Have a second sampler quilt that uses the scallops. Will post when it is pieced, soon.
