My medium of choice at the moment is an Apple iPad. ePaintings I create on the iPad can print up to 40 inches wide. Also, I've been doing pencil drawings for 30 years and have posted a couple of those as well.
I encourage you to click through the printing, matting, and framing options for the art on this site. It's fun to see how the right mat and frame can transform an image.
