The Material Safety Data Sheet (MSDS) for Elmer's washable glue states:

PRODUCT TYPE: Chemical Product and Company Identification
Whikipedia states:

So contrary to the urban legend, there is no cornstarch in Elmer's washable school glue

Thank you for clearing that point up, Mcwillia. The urban legend about buggies and creepy-crawlies can now be put to rest and lots of previously frightened people can discover the joys of washable-glue!

I am a new Elmer's School Glue convert! Earlier, I had used it to match up open seams only. Just a couple weeks ago, I basted the batting and backing together in sections (roll up the batting first, drizzle the glue very lightly on the backing, one section at a time, then roll down the batting to the end of the section and pat it down gently. Repeat this until the backing is done. Worked like a dream!). This past week I used the glue for the binding for the first time. It is accurate and it is a timesaver! Thanks, everyone, for cluing us into Elmer's School Glue!

I have read the messages about glue basting and have a question. Almost all of my quilts end up on the wall instead of on someone's lap. I have never washed a completed art quilt. If I were to glue baste, which sounds really useful, would it be a problem to leave the glue and not wash it out????? OR, is there a way to remove the glue without washing the quilt? Since I make art quilts, I seldom to never prewash my fabric..... I am very worried about bleeding.

One more thing - I have only recently joined this quilt board, but have been reading it for months and cannot believe how much I have learned from all of you. Thank you for sharing your knowledge and experience!!!!!

I would be hesitant to use it if I wasn't going to wash it out. If you have bigger dots it can leave a hard bump and mine smelled a little like glue before I washed it. And I do think bleeding might be a problem.

I sandwiched a quilt just yesterday using Elmer's school glue. I clamped the backing to my 30 X 72 table. I laid the batting on top and checked to be sure it fit as planned (no surprises at the end). I re-rolled the batting and started laying down dots of glue and unrolled the batting as I went. I turned the piece over and laid dots of glue on the batting side and pressed the quilt top on in smoothing with my hands. By putting the top on last I could be sure that it was straight and had straight lines and square corners on the blocks. I thinned the glue with 25% water so it would come out of the bottle easier. The process took about an hour. I let mine air dry on the table while I did other things in preparation for the quilting. I have done my quilt sandwiches this way several times. Those heavy, cumbersome safety pins have joined the relics bin for me! It washes out completely.

I found 4 brand new bottles of Elmer's School Washable glue at a garage sale yesterday for .10 each. Snatched those puppies up. I'm going to try it today on a quilt that's ready to be FMQ. :)

I seen the tutorial for Elmers Glue on the board but forgot to save it. Could someone please post the link again. Thank you so much for all your help. I so appreciate everyone here. You are my extended family.

I haven't tried it but I am planning to do that soon..as soon as I remember to buy the glue.

Okay. I'm convinced. Will try the glue method the very next time because it sure sounds easier!
