School Glue Problem - A Cautionary Tale!
 

I've used School Glue successfully several times on bindings and for basting. BUT I created a problem for myself the other day when I was basting a sandwich for a small project using Kona solid fabric backing and a thin polyester batting. I drizzled a bit of glue onto the batting and spread it with my finger and then placed the solid backing on top and pressed it down with my hands. Then I decided to hurry the process along by pressing the sandwich to dry the glue. BIG MISTAKE!

Apparently the glue hadn't soaked into the batting sufficiently and the result was a series of dark "glob" marks on the solid fabric. I tried spraying the sandwich with water to dissolve the glue but to no avail. I then pulled the sandwich apart and tried unsuccessfully to rub out the marks. I finally had to create a pattern on the solid fabric using fabric crayons so the marks wouldn't show! The improvisation worked out just fine and the project was saved but it was "white knuckle time" for awhile.

So....I think that my mistake was twofold: first assuming I'd spread the glue thin enough to begin with, and then the ironing -- I suspect that the glue actually got scorched when it penetrated the Kona and was ironed.

Lessons learned: 1. be VERY careful using glue on polyester batting by making sure it is spread VERY thin 2. don't press the sandwich while the glue is wet.

Great advice, thank you!!!!!

Did you wash it after you finished it? It is my understanding that the glue washes out and you shouldn't have it showing on the backing.

I've had glue marks showing on the back when I've pressed to dry the glue. I always wash my projects when finished and have never had the glue marks show through.

Sorry...double post.

I think another QB member warned us about using Elmer's glue with polyester batting.
If I recall she said not to iron the glue to the batting...just let it dry.

and don't you do dots, not lots to spread? I only tried it for binding and evidently used too much. it ironed through my binding. I was not happy and I did dots.

I have only used it for the binding, I iron it to hold it in place till I sew it. so far I have not had any issues and have been doing that for several years. I still use 505 spray for my basting. I wait till its half price and free shipping at Joanns. I still love 505 spray.

The brown scorched areas of glue will wash out....been there, done that

I only use glue sticks and let it dry overnight before doing anything else. Quilting is teaching this very impatient person to be a little patient!!
