To add some interest to the tree, I've used one of my favourite techniques (ooh, techniques starts with a T too!) - foiling. I dotted the image with Tonertex (ooh anther T!) pen and left it to dry, then rubbed a special metallic foil over it. First I used dark brown, then repeated the process with copper, and finally with gold foil. You can buy the special foils and the Tonertex pen from Foil Play. Instead of doing the whole tree I highlighted just a portion of it by stamping a second image, die cutting a circle from it, and foiling only that, sticking it in place over the original image with 1mm foam pads for a little definition.
