|Cut an colored envelope|
One of the other alterations that I made was that I cut out the envelope first and then used the cutout for the stencil design. This allowed me to be sure to get the image/location that I wanted on the face of the envelope. When I stenciled and colored the entire sheet, I couldn't control how the images appeared on the actual envelope. By cutting the envelope first, I was able to guarantee the placement of certain parts of the stencil.
The trick for this envelope is that I sprayed the envelope with fixative after drawing the outlines and the coloring lines. I then let it dry overnight to set. When I colored with the Copic markers, there was much less feathering of the outlines. I think that I am getting pretty close to perfecting these techniques.
