I have begun the layout of John Q quilt, by spreading out a white sheet to be my "design" wall. Trust me that the sheet is white, very white, but it is picking up the tan wall paint and giving it a tan hue.
Then using my iPad, and some general direction from another layout from the stained glass denim quilt, I began to layout the different sized squares.
To this point, which is about 55" X 58". This is a starting point, because I need the quilt to cover a double bed, so about 80" X 88". Right now we are working on getting the randomness to the liking of the client.
