FYI for anybody still interested in this question.

I used spray to adhere something I was thread sketching last week. I washed the piece thoroughly in hot soapy water right after the embroidery was complete. Today I started to use the piece, and lint was stuck here and there to the gummy residue that remained on back. I soaked it again, washed it again, more soap and water, and added a soapy toothbrush to get tougher with it. A little more came off, but still a fair amount present. It has now transferred to my ironing surface as well. So, I am pretty sure it would not wash out from the inside of a quilt if I am applying direct action and can't get it out.

Between the initial fumes and the semi-permanent residue left behind....not too sure this is a good idea for me.

I've found it best to not wash right after use, but to allow about two weeks of airing out first. Even then you might have some gluey lint stuff if you sprayed heavily. particularly check during drying (like for baby quilts) and remove while damp if you can. I always sprayed too heavily at first -- for years even. I had access to a long arm for several years and didn't use spray baste. A couple of years ago I started doing them at home again, and the first one (even knowing what I know) I sprayed so heavily I waited two weeks just to quilt it -- good thing I wasn't on a deadline. It might just be my vision issues, but if I can see where I've been, I've sprayed too heavily. If it feels damp or discolors the fabric, that's waaay too much.

While I don't usually use drying sheets, this might be a time I'd consider one if you are on a deadline and about to present a quilt to someone.
