Shelf Life and spray bottle question.
Thought I'd chime in on the shelf life and spray bottle question. My husband (former teacher) bought a gallon jug of washable glue several years ago for his Chemistry class. He quit teaching May of 2016 and I inherited his partial jug...still worked great. So, shelf life is several years at least (as long as you cap it and don't leave it in extreme heat most likely). Also, I have diluted it 50/50 (more or less) and tried it in a spray bottle, still came out in clumps, not a fine spray...so that one doesn't work. I saw a lady on Youtube who says she uses it in one of those metal pumps made for oil (to replace cooking spray) and gets a fine spray. I haven't been able to locate one locally, someday I will bite the bullet and buy from Amazon. I don't spray baste when hand quilting, makes the quilt hard to quilt through. I do use it for basting seams where I have a lot of points that I need to match up. Just remember to set it with the iron so it doesn't gum up your needle.
