Yes, if you want to use the quilt. I think I've read on here that it wouldn't be necessary for wall hangings.

I use just the smallest amount of Glue when I glue baste. Like Milli says, little drops, really little, of the glue. It doesn't take much. I've done about 7 this way and love it. I usually let it dry overnight because that works for me, but will try the hair dryer just to see.

I glue the back to the batting, then turn and glue the top to the batting. I dilute the glue with a dollop of warm water and it streams out very thin. If I had to pin or sew baste I'd be doing it for a few hours so waiting an hour for the glue to dry is still saving time. I know I will never ever pin or sew baste anything bigger then a potholder.

You may be using too much glue. I hold the tip of the glue bottle right next to the batting and run the thin, thin, thinnest line of glue about every 6 inches. The tip will often pick up a little bit of the batting which trails along and this is even better. I have never had to wait long to begin quilting.

I have done about 6 or so quilts with washable glue and have never had to wait more than an hour for the glue to dry and start quilting. I start by laying down the batting and gluing down the top...wait about an hour then flip and do the same with the backside. I use the poly batting for most of my quilts, so ironing is out of the question, but I bet the blow dryer would help speed up the process! I don't think that I ever get to quilt undisturbed, so that hour of drying time is usually spent working on laundry, cooking supper, cleaning up the sewing room, etc. DH says I multi-task too much....LOL.

I love this method and also the home made spray glue kind too. Patience is a virtue that I have learned with all aspects of quilting and these methods method have saved me hundreds of dollars, no messing around with basting pins and a secure sandwich when I do my FMQ. I always wash my quilts when they are finished and both methods come right out. I use the time in which a quilt is drying to decide on my next project and then start gather my thoughts and materials.

I hold the glue bottle up as high as I can and stream a fine line all over the top half of the batting, smooth the fabric on, then do the bottom half. Diluting the glue with a bit of water makes the glue easy to stream in fine lines. I have fun writing my name or the quilt receiver person's name in glue or doodling big designs with the glue. LOL
