LOVE using glue! It really makes life so much easier, and flatter, and less wiggly, and neater, and... The one thing that I really like is I do QAYG and there are just some fabrics that tend to stretch when quilting on them, and using glue right where the stitching will be so prevents the stretching and movement of the fabric when sewing on it. The only draw back that I can think of when using glue is you have to wash the quilt when you are done to get the glue out. But I always have pen marks that need to be washed out, so i guess washing before use is par for the course.
