I've not made a large number of quilts -- I'm just a newbie. I will say this, I am asthmatic, and the spray basting is absolutely out of the question. I'm still learning, but have had no problems with pin basting. Of course, I am generous with the pins! Whatever method you decide to use, sandwiching the quilt is the hardest part of making a quilt JMHO! I have qualms about the glue-basting -- first of all, washing a quilt (especially king size) is not something I would want to do in my domestic washing machine. The only laundromat with the giant-sized washers is clear across town (about 25 miles one-way) and those machines are very expensive to use. I am currently working on a project to make sandwiching very easy -- let's home it works!
