Good thing to confirm. We might try find posts on this board concerning glue basting and see if anyone has mentioned machine problems using Elmer's.
I have used it to help piece blocks with stubborn points, etc. and have no trouble. I could see if the glue was put on really think one might have machine problems because it will get hard.
A fellow board member said that she will dilute the glue in a spray bottle, put a thin thread of glue on fabric and use a very small paint roller (trimmer kind) to spread the glue. A very little goes a long way. This would be no worse than a spray basting product.
I will be following this thread to learn what our QB friends have to say.
