I don't use painters pyramids, only because I don't have any. Also, any spraying that I do (glue, paint or finish) I have to do outside so I use a lot of natural alternatives, rocks, sticks and logs.
That being said, I quit using spray glue. I find it really messy on small jobs (too much overspray) the fumes are really awful and waiting for a "nice" day to spray during a Minnesota winter isn't fun. To stick a pattern down I use glue sticks, the kids craft type, simple ans easy. To stick a project to a backer I use hotglue most of the time (wood glue and super glue are my other methods occasionally).
