I spread the glue in thin lines about 3-4 inches apart onto half of the batting....the lines have a tendency to turn into dots of glue, which is ok....the smooth out the top/backing, patting down well, then repeat with other side....at this point it can either air dry or be ironed dry....then flip and add the other piece in same manner....by spreading the glue onto the batting, you always see if there are any issues with puckers/gathers and can be easily fixed before glue dries....any globs of glue can be smoothed out with your finger....never any shifting of fabrics, and will hold until you wash the quilt when done....may not be easy for handquilting, but great for fmq.
