Using the first idea of quilting in layers: What about after washing? Won't the layers shift outta place?
Would it work to quilt all but, maybe 4 lines? (2 in each direction on both layers) Then position them together, matching (close enough) the top and bottom along the lines and THEN quilt the missing lines so as to stitch them together? (if you know what I mean). Or would that be to much fuss?
I've tried glue before, but have run into machine problems with that and decided never to use glue again where I stitch. I glue, but not in stitching areas. Thanks anyway.
