Here is an ATC, using an image from Vintage Resources (it's a lovely site and appreciates a donation for your use of thier images). I inked the white cardstock with blue and green inks, cut out the image and attached her with a thin smear of Liquetex brand Matte Gel Medium. Then, I applied another tiny smear of gel medium to the lower part of the ATC, over the photo image and blended blue ink into it while the medium was still slightly wet. Then I stamped the text and swirls with red and black ink and let it dry.

This lovely little girl image is from Oxford Impressions, stamped with black ink onto matte photo paper, hand-colored using a sponge & blue dye ink and attached (with gel medium) to a brayered and stamped background. The egg and "dreams" are likewise stamped and attached. No "fancy" stuff with blending inks into wet gel medium - just straight adhering to the cardstock.
I really love this Gel Medium stuff! I have the matte formula, and I think I'll have to go get the glossy formula, too!
