Here's a new magazine from Scrapbook Stamp Society called "Color and Create". The introductory issue just became available both as a printed edition ($9.99 + S/H) and as a digital download ($2.99). It features many hand-made projects that uses digital downloads of line art that crafters can color with such media as Copic markers.
Some of my line art digi-downloads and stamps are featured in the projects. You can order either the printed copy or the digital download copy at this link.
