Ah, the poor back of a painting. It can be sadly neglected by many of us who don't have our work framed. But why not use its valuable real estate for something more interesting?
- Glue special keepsakes that mean something to the back. When I painted my piece "Don't Be Afraid To Take Chances" I kept the original fortune and glued it to the back of the piece, to one of the stretcher bars.
- Write down the Title, Size, Medium, Year the piece was created, then add your URL, that'll allow the paintings owners to see other works by you even years later!
- Paint or Draw something fun on the stretcher bar
- Cover the back with wallpaper or something creative
And of course, the most important thing: String it neatly and professionally for hanging:
- DO use strong D-rings, sized appropriately to carry the weight of your painting
- DO place the D-rings far enough down from the top that the 1-inch or longer hanging hardware on the wall won't show above your work
- DO consider coated wire: it looks nicer and it doesn't cut your thumbs as you put it on the D-rings
- DO use a neat knot to attach the wire to each D-ring, then loop the wire around tightly at least 4-5 times and trim with wire cutters as close to the main wire as you can
