I made some folded ATCs a couple of years ago which you can see here.
Today I decided to make another trifold ATC. I cut out a sheet of paper 3-1/2" x 7-1/2" and scored fold lines 2-1/2" in from each end. Also choose a sheet of paper used in my spray box to cover the inside of the card.
Painted the outside flaps with Twinkling H2Os and blended the colors by spraying with a fine water spray. Then stamped on some images with brown StazOn ink.
Cut half to fold in a butterfly embossing folder so it would slip over my card where I want it and embossed the image. Did another butterfly embossing folder on the other side.
Colored the raised embossed areas with Twinkling H2Os using my fingers to apply the paint. Then I cut away the card above the embossed butterflies on both side.
