I know a lot of you dilute the glue, or spread it on with a brush....but for me it is straight from the bottle, full strength. I hate making more work for myself if I don't have to. I simply open the tip wide open, turn it upside down and squeeze while moving back and forth across across the batting (about 12" or so up from the batting)....important to apply glue to batting and smooth fabric onto batting, then pat down well. You will not get wrinkles this way and by applying in a grid of lines about 2-4" apart, there is no need to pin because the fabrics/batting will not shift. Some will use the iron to dry the glue, but I just let mine air dry for a couple hours, then flip to do the other side....plus ironing dry probably not advisable for poly battings.
