I recently glue-basted a massive king size quilt - 10 feet square. I taped the backing down, spread the batting first, then peeled it back in halves to sling glue down on the backing; I was aiming for something like picture A but it was a lot messier than that. Then repeat for the top and just let it sit and dry for awhile. FMQ'd the whole thing and it turned out great! (aside from my poor FMQ skills) I actually have it on my bed right now and I haven't washed the glue out - my washing machine is too small to fit that monster but my DH couldn't wait to have it on the bed, LOL, so we're sleeping under a gluey quilt until I remember to take it to the laundrymat. I can't tell that the glue is still in there at all, and it got pretty heavy in spots. I didn't dilute it, either, just squeezed it out of the bottle in a thin drizzly line while I stood above the quilt and just sort of slung and flung it around. It was kind of an experiment, to see how sloppy I could get with the glue and still have good results...answer seems to be - really sloppy!
