Hi All, I found the old thread on spray basting with Elmer's glue and read through it. It didn't really have any of the answers to a couple of questions I have so I thought I would revisit this.
1. How do you keep it from coming out of the spray bottle in a stream? When I tried at test block after making the mixture (50% glue, %50 H2O and a few drops of dish soap) and had the nozzle on spray, it came out in a stream.
2. Should I add isopropyl alcohol or more water to make it thinner?
3. Do you heat set after spraying? I am doing a very large quilt and don't want it to take days just to baste it. I am also using polyester batting so I know I need a cool iron.

Thanks,
Shari
