Hello Schoolteacher, I use a sash less quilt as you go method for most of my quilts. - even did a Double Wedding Ring and quilted as I went and joined each row to the next. I looked for a video that was close to the way I do mine, and this is the most similar
http://www.youtube.com/watch?v=I_qyb7XxY4k However, I don't use the original stitching line she used.
I usually cut my batting and backing an inch bigger all around and trim it back when joining. After quilting each block, I join the fronts together using a 1/4 inch seam allowance and press. From the back of the blocks, smooth down the batting and it will overlap. Carefully take your scissors and slip them between the front fabric and the batting and cut through the overlapped batting. It doesn't matter if you cut straight or crooked - the cutting of them overlapped makes them join perfectly! I whip stitch my batting together instead of using a special tape. You can do the back seam like it is done in the video, or slip stitch it by hand. For me, that depends on how I want the front to look.
I have given up fighting to do quilts under my sewing machine. This way I find that I have less UFO's as when they are done - they are done!
Hope this helps.
