I get confused when the squares are sewed together. I know you have added the material between the squares, but what if you don't want that look.
I can't remember where, but I have seen one were the backing is laid first than the batting.With the top, the first row is(it was strip of fabric) bast on, (you roll up the botton of the backing and batting while you sew the Next row to the frist row. As you unroll you sew on the next row. I don't know about doing this with a large quilt but it looked so simple for the lap quilt being prepared. Has anyone seen this method before are tried it.
