Cat skull update and new 'support system'

I remembered that I'd once heard a watercolor artist mention that she stretched her paper over a frame like you would linen for an oil painting, so I googled it. Apparently this isn't as uncommon as I'd thought when I heard about it so I thought I'd try it. I now have 2 5x7 watercolor paper canvases... so far I like working on it alot, no warping, no having to tape it down, it's lovely. I'm doing the cat skull and I think it's coming along ok so far.... here's a work in progress shot...
