I also thought that brown would be a nicer outline ink than black. I need to buy an archival brown, because this brown started washing away as soon as I hit it with a waterbrush. I was just trying to soften the yellow and orange marker I was using, but the lines started going, too. After looking at how fuzzy it was getting, I decided to stamp over it again to sharpen the lines. It gives a dimensional look, don't you think?
Of course, after doublestamping the flower, my sentiment looked faint, so I stamped over it with Versamark and clear embossed it. I didn't line that stamp up any better than the flower one, so it has a faint shadow look to it. Versamark was also used to stamp the background.
