Hi, Rebecca -

This reply addresses the issue of undried tempera paint lifting from the canvas when painting over it. If you use pigment rather than dye in your work, you might want to try polymerizing/drying your paint with a source of ultraviolet light (lamp or sunlight). Photopolymerization might give you an edge with regard to the waiting time between painting over a layer of egg tempera, or even egg-oil tempera. Caveat - most dyes (and some pigments) will degrade and fade when exposed to ultraviolet light.
