I am very partial to 16 patch blocks using 2 1/2" squares (cut)
Always including 3 solid blacks scattered amongst the others
I sash with black or navy, using a 2 /12" cornerstone of a scrap.
Have also made the same quilt with 3 1/2" (cut) squares
Many years ago when I went regularly to Quilting by the Lake in Cazenovia, NY quilters threw away large scrap pieces.
After the classes were over I collected large scraps from wastebaskets, enough to make a double Ocean Waves, which I've called The QBL Wastebasket Quilt
