Not sure if this will be helpful or if you know it already, but when I use the glue stick on my starched fabric, I press it before I stitch. I think if you starch, then glue stick, then drop your dogs and use FMQ technique, you will be able to avoid any puckers. FWIW, IMHO, its easier and still pretty cheap to use spray starch from Walmart than to use the kind you dilute yourself, (forgot the name.) It was nice and stiff, but my iron was all gunked up. Wasn't worth the clean-up.
