I tried a couple of techniques with these stamps, and a few color schemes but wasn't happy with any of them. Then during a biographical presentation I was watching, the speaker posted a sepia lithograph of the subject's home. That immediately inspired me and I decided this set should look like an old lithograph.
The images were stamped on the Tim Holtz Stamp Platform using Ground Espresso Archival Ink. It's my new favorite Archival ink color. I used it a lot with the Halloween stamps this year. In order to use it on some large stamps like these, I purchased a DIY Custom Blend Distress Ink pad and loaded it with the Ground Espresso Archival Ink Reinker. Then I could use an individual ink pad to make sure these images were completely covered in ink before stamping.
