I have been using the Elmer's glue since I read about it on this board. I spread my 3 layers together making sure to have some overhang of the batting and backing on all sides and drape it over my sewing table (which is a small folding table). I pin it across the middle then roll back the top and start gluing a little at a time. I have been ironing each section as I glue, but I don't think I will do that anymore as I find the top will be a little warped when I start sewing...like it has been stretched and I wonder if that is the ironing?
