That's exactly how I do it....I love the idea of QAYG but don't like all the seams on the backing. This way there are no seams on the back.
Don't be afraid to divide your batting as much as you need to. On a king size I divide width and length into more manageable sizes for my home machine. Then I fold the quilt top into 4 or 5 inch width and do the same to the backing. Pin folded top and backing together to keep from coming unfolded. I hope that's clear.

try and goggle "quilt as you go" and you'll get lots of examples...there is one that I have tried. its with 2" strips between blocks. I did this with a crazy quilt and it worked very well.

I HAVE NOT TRIED THE METHOD THAT YOU HAVE LISTED FROM PENNY HALGREN. I USUALLY ONLY MAKE QUILT AS YOU GO QUILTS AND LOVE THEM. I MAKE ALL MY BLOCKS ABOUT 2 INCHES BIGGER AS THEY SHRINK WHEN YOU QUILT THEM. THEN I SQUARE THEM UP TO THE SIZE OF THE FINISHED BLOCK I WANT AND ATTACH THEM WITH THE SASHING METHOD. MY FAVORITE WAY TO MAKE QUILTS AND HAVE DONE 2 PHOTO MEMORY QUILTS IN THIS METHOD AND THEY HAVE TURNED OUT GREAT AND QUICK. GOOD LUCK WITH YOUR PROJECTS.

I did it years ago, don't remember having any trouble with it, at that time I only hand quilted without a frame. I'm going to do it with machine, if I live long enough - lots of quilts planned before. I'm sure with new methods you will have good luck with it.

My friend showed me how to do a quilt as you go quilt and it is a lot of fun, you do it in triangles and end up in a squares. Lot's of fun. I'll try to post a picture.

I regularly do QAYG. Especially for childrens quilts. It's I really like how I can set myself little goals. ie: 2 or 3 blocks a day....

Here is a link to one that I did last year

I also did a larger one based on the French rose pattern. I absolutely loved this one that I made for my grand-daughter Emily. I love that I could machine quilt it myself and not have to send it out.

There is another option, which is quilting in sections. See Marti Michell's book, Machine Quilting in Sections - http://www.amazon.com/Machine-Quilti...7225218&sr=1-1

I used several of the methods in this book on all my large quilts (until I got a longarm) and it made the quilting process much easier.

I'm trying QAYG on my upcoming baby quilt project. It's my first time to use QAYG so I have enjoyed reading this thread. Anyone else got ideas about QAYG?

another idea is the "fun and done" quilt...thats a real good pattern.

Cotton Theory is one method but it is very stiff.
I have made a Fun and Done but it has one flaw. You only have one seam holding your blocks and rows togather and mine is already coming apart in places. It is the easiest method I have seen though.
