I have used hair spray to baste a wall quilt, and it worked fine. However, I don't think it would hold for a bed-size quilt.

there are other adhesive spray you can look for I bought quilt basting by tailor & fast tack by sprayway I got sprayway at walmart on sale for $4.50 for 13 oz can I am not sure what i paid for tailor. walmart also had another spray that was a good price you don't need to buy the expensive ones.

I will stick to the 505, it sprays on so nicely and stays sticking until I am done quilting. Some of them have been very large quilts and I have not had a problem. I do watch and get it on sale if I can. If by chance I venture into a quilt store and they have 505 at a reasonable price, I pick up a couple of cans. I have bought the smaller size for 12. and that is here in Canada. Mind you yesterday at a shop hop there was a can for 19.00 which I thought was a little pricey. It is good stuff, trust me I have tried other brands.

Elmers Glue
 

I just recently started using Elmers glue. I bought basting spray and it was not lasting very long, and for $15, I needed to rethink the process, so I decided to try Elmers. WOW! I'm in LOVE with that process! Elmers glue is so manageable because you can place it where you want it. I plan to use elmers every chance I get. Phooey on basting spray!

I use 505 all the time! it has little odor. will allow you to reposition, and will not come apart as you fling the quilt around when quilting. Thanks for the heads up about Sewfor less changing manufactures. I just got some and the can was different and the price much higher..Hope it is as good as the original.

Sewforless
 

If you look at all of their temporary adhesive sprays, you will find a new brand that is actually less expensive than their "505". I don't remember the name without checking their website. I believe it was only $10+. Let me know if anyone has used their new product please.
