In my experience, the only time I glue baste now is if I am doing wall hangings, or putting the binding on a quilt. I found that glue basting sections of a quilt wasn't strong enough to prevent the top from coming apart from the batting or shifting. Didn't work for me, but doesn't mean its not a good idea. I now pin baste starting at the middle of the quilt and go to the edges, pinning about every 6 inches. Worth it to me to have great placement and control of the whole quilt sandwich when moving the quilt at the sewing machine. I do iron the binding after using a very thin layer of glue. If the binding gets placed incorrectly, I can pull it up, use a damp paper towel to wet the binding again, and then iron to secure it. I have never diluted the glue, and I glue a couple feet of binding at a time before I iron it.
