Well, free except for your supplies.

If you have ever been to Baltimore, MD you will see painted screens (windows, doors) that are beautiful. Here's a how to -- for your neck of the woods!

Jenny Campbell was born and raised in Baltimore, Md., and when she moved out of the area into a more rural part of the state, she wanted everyone to know of her civic pride for her hometown. With a great deal of artistic talent and a broad knowledge of the Baltimore-born medium of screen painting, the plain window and door screens of her home were soon replaced with a captivating homage to the city of Baltimore. She now spends much of her free time putting a contemporary spin on the old folk art by creating funky painted screen clothing and as we’ll see, miniature, photo-realistic framed screens. (via HGTV)
