In the last month I have spray basted two really big quilts, one is 108" square and the other is 96"x105". I cannot fathom basting them with school glue. Honestly, I have to admit that I can't think of an instance where I would use school glue for basting anything. I bought that little bottle of glue with the really fine metal tip and have not used it either, but then again, I haven't done anything with applique. Getting ready to do a landscape so it might come in handy for that.
