I am about to try Elmers school glue. It worked on smaller projects, I don't see why it would not work on a large one. Will post results!

I would think you'd break some needles -- lol. I can't wait to hear how this works out, but I'm not giving up 505 spray basting now that I've found it. I've been told that you can use it inside if area is well ventilated. BTW, to those of you new to 505, don't over use it. A little goes a long way. It can gum up your machine.

I've been using 505 exclusively for some time now. I am, unfortunately, not light handed with it. Particularly on the edges. I let it dry for at least a day before I begin quilting and I have never had it gum up my machine.
However, this being said I have had partial cans sitting and sometimes the glue can get a little bit thicker as it gets older. To compensate for this I just give it a little extra time to dry. I think making sure that the adhesive is dry is key.

My Brother sewing machine has a big basting stitch on it. I am going to try that one on my next quilt to see how it goes. Usually, I spray baste with the cheapest spray possible and they all turn out ok and don't come apart even if left for months.

Personally, I do not baste anymore. I used to lay the three layers on the floor, baste my heart out, and kill my back bending over for such long durations. I now lay all three layers as I want them, and use safety pins while making sure there are no puckers. If I have time, I'll put that quilt into the floor stand...if not, then I just roll it up tightly, and set it aside for quilting later. The glue thingy is a little out of my budget, so I have learned to improvise.

I still have problems basting my quilts and might try the spray-I really enjoy reading all of the comments -what piles of info!!!!

I pin my quilts, then quilt any straight lines about 10-12" apart, then I can take the pins our and quilt later iwhen I want to.

I use the spray baste from Hancocks and I don't think it would take a whole can to baste a queen size, but I don't make quilts that large so I'm not sure. The regular price is about $12.00 I think and I always use the coupon or get it on sale. I do several twin size from one can. Also, I always spray baste using the foam board insulation pieces and open windows when I work on the inside. One day I moved everything outside and sandwiched 8 or 10 quilts...easy peasy.

Nancy Zieman showed basting a quilt with the fusibles and I wondered if it worked well. Bellaboo, do you have good luck doing that?

There are soo many good ideas from everyone here. I like the idea of having the longarmer baste the quilt for me and have even ask her what she would charge. She said $30 - $40. I probably would have her do it for that price.
