huh?? usually you make your rag squares as you go and sew them together which leaves the rag seam on one side of the quilt and no seams showing on the other. it's done!! it's a quilt as you go method. no adding backing afterwards.

The picture looks great. I noticed you have designs on each square. Did you put two or three layers on each square? I only have one layer so, making the design on each square will not be very noticeable. That is where I made my mistake. Making only one layer.

It wouldn't be very heavy if you didn't add a backing of some kind. Of course, if you like the way it looks you could leave it alone and it would be a summer quilt. If it is one layer of flannel, wouldn't it be just fine to toss over you legs on a cool evening in front of the TV?

Since it's aready sewn together you could add a backing and tack it in the middle of each square.

Whew, that makes me feel better, yes it will be light like a thin blanket. I may go ahead and put a sheet on the non-raggy side. Thanks.

LOL the first rag quilt I made I did add batting in between the layers. THOUGHT I had the batting small enough so it wouldn't show. WRONG! i had all these little white tufts sticking out everywhere. Looked a bit funny but boy is it warm!

well not sure why you want only one layer but yes, i did my quilting designs on each square. mainly because i did add batting and another fabric for backing. i had to stitch something to keep all three layers together.
now if you are sewing squares together with the seams then being snipped so they would "rag", i guess you are done. no design would need to be stitched because there would be nothing to hold together.

Do as bakermom said, add your backing and tack or tie in each square. I would think it would be extremely difficult to STID at this point.
