I have this pattern and it is on my bucket list of quilts to make. The blocks are 20" I believe. I looked on
Pinterest and there is a pic of this qwilt in a 3 x 4 block setting which would make it 60 x 80, a nice lap sized qwilt. Not sure how much of a rectangle qwilt you were after.
Some software is adding a link when the word 'quilt' is used. It is something called Viglink. I have adblock software added. Not sure who VigLink is are why it is adding links to my post. I will investigate this. Meanwhile I spelled the "Q" word differently.
