I've been doing QAYG for many years and have used a lot of different methods. I like sashing, but I also like a quilt without sashing.
I'm using this method now, based on this video that I saw -
Halo Inspirations It is QAYG without sashing. I needed to revise it a little for the end blocks around the edge of the quilt as I'm keeping the batting to the edge on the block edges (sides) that will have binding on them, so my binding will be full with the batting. Basically you cut the binding the same size as the finished block -- you can skip part of the video that shows you how she fixes a mistake she once made, but other wise since I'm used to doing QAYG it was easy for me to improvise. I think this one is going to be my favorite for when I do QAYG without sashing.
I recently tried a different on before I found this (one above), but it ended up being too bulky and still has sashing on either the front or the back.
I also have done
Carolyn Forsters QAYG with no sashing -- it is a very short video so I got her book to get the entire instructions The book is:
Quilt As You Go: A practical guide to 14 inspiring techniques & projects I think this one was a little time consuming and you have to be really careful not to accidently cut the quilt front when you are trimming batting and the like.
This is why I like the one on Halo Inspirations better. You trim the batting to the correct size to begin with. I also left the backing a bit bigger than she did on the Halo site, so that it wasn't such a small foldover.
