A friend was over and she picked up my hexies. I said you can glue baste the fabric to the papers if you want. I thought she knew how to glue baste a hexie. LOL She glued covered the whole hexie to the paper template. I never did get the papers out. Thank goodness it was easier to toss and make more then to try to save them.

If you don't want to use water on it use your iron, the heat will loosen the glue. I do this when I glue baste my hexies and they stick to well.

I don't know about that. It says in the videos from Elmers to Not heat-set the fabric as it would create a permanent bond.

Are you sure it was Elmers washable school glue. This is the way I release my glue all the time but only if it is Elmers School Glue. Forgot to mention that I release the glue while the fabric is still warm.

. I don’t think this applies to the washable school glue. Even if I hear set it, it still washes out. At least that has been my experience. Not talking about Elmer’s Glue All. Just Elmer’s washable school glue n

Here is a video from Elmers.com that may help. If you haven't ironed it, you may have a chance. It may take several times to get it out. If this doesn't work, maybe call Elmers and see if they have any solutions.
So sorry this happened to you and your quilt.
Best of luck in saving your work.

Sorry this happened and hope you can figure out a way to make the quilt and sleeve "all better." Mistakes happen to all of us. Those mistakes help us learn and get better at making quilts. You've had a lot of advice, so hope something helps.

If you glued just in the seam allowance and not the entire sleeve why not just leave it.
