Here's what I ended up with. The fabric is laminated with epoxy. Need to fix the bits where my PoorBoyBurst standoffs left some light spots, hoping to get away with some light sanding. Then it's time for some clear lacquer. The smaller light spots are epoxy sandthroughs, not going to worry about those. Just a little brain damage, that's all.
I'm planning to cover the back of a Tele project with fabric. However, the body has a rather large roundover (1/2" or 3/8", can't remember). I can't figure out what to do with the edge of the fabric. The sides will be a solid colour. I'm planning to do a PoorBoyBurst(TM) but the transition from wood to fabric worries me, I'm afraid there will be a visible step made even worse if the edge of the fabric does not follow the guitar outline 100%. The excellent "Material finishes" tutorial by Brian doesn't really cover this as the guitar in that one has a sharp edge.
