I think I know what my problem is with this beast of a quilt. Every single time I used cotton batting with Elmer's school glue and it worked like a charm. After reading your posts (thank you all very much) a bulb went on in my head - my batting is poly not cotton. I did not have cotton handy and I was itching to work on the quilt so I used poly batting that was lying around in my sewing room for I don't know how long. Mystery solved. Elmer's School glue and poly batting do not go well together, at least not for me. I had to get up and walk away from it earlier today because I got very frustrated with puckers which seem to be multiplying in bacterial progression. I am afraid to even think it but I may have to unglue my quilt and start all over again. OR I should cut my losses and accept the fact that I have became a true quilter by creating my first UFO. To quote Scarlet O'Hara :"I'll think about it tomorrow".
