I'm participating in a Leaf swap hosted by Nanner on atcsforall.com, and am having fun playing around with the watercolor layered backgrounds. These all use a base of watercolor wash, and then layers of stencil shapes also with watercolor. Here's where I am with four of the leaves - these are all around 6-1/2 inches long and are 140# watercolor paper.
For the one green leaf with tree, I used a tree outline stencil and walnut ink spray. I kinda like it, but need to work it over a bit. I think a bird will end up in there somewhere. I'm debating how to edge all the leaves with color without making a mess and/or ruining it. :)
This is a background using Twinkling H20's - which may also become a leaf, or perhaps it will be something else entirely. We'll see!
