As of June 2015, free scherenschnitte, or paper cutting, patterns are online at Martha Stewart, Extreme Cards and Papercrafting, and Scherenschnitte. Martha Stewart's site has a video tutorial that demonstrates how to make a delicate paper heart from a printable pattern.
Extreme Cards offers a picture with hearts and doves. Site users download patterns in Adobe Illustrator or GSD. When two of the designs are combined, they form a pop-up card. The Scherenschnitte site has many of its templates organized into categories such as flowers, animals, children and a variety of holidays. Clicking on a small photo within a category opens up a large template.
