Re: Framing and Displaying Work
I find that the fixative makes it look good, removing blemishes and evening things out, but doesn't really protect your work. I use about four layers of spray varnish and everyone has their favourite brands. I don't much care. I also use gloss because even after four coats, it's never actually gloss, more a satin finish. However, a lot of people like to start with satin. I like the gloss because it accentuates the texture of the scratching on the boards to some degree.
However, varnishing large pieces is much harder than smaller ones. Because of being in Australia, the largest I work with is 16x20 simply because the larger boards are ridiculously expensive to get here, but your large pieces might be more difficult. Try not to varnish in a cold room and keep away from humidity. People have complained about those things on here before. Maybe someone else will chime in but in South Australia, I don't really have those problems. I also make certain I work in my most dust free room because dog hairs and specks can be a pain to remove.
