My quilt, after quilting and washing, ended up being 47" x 60". I used a 14 x 19 block layout, then a 1" stop border of light shirting and then the scraps from the quilt for the last border.
I started with 15 x 20 layout, but after cutting the pinwheels with the Twister ruler it ended up being 14 x 19 layout. The part you lose around the outside edges after cutting with the ruler is what I used for the border.
