Knowing how to display your art and even what to display as art can be a bit tricky. Probably the thing I see most often is small artworks on big walls - so they are very out of proportion and then artwork that is hung so high you cannot actually see it. A lot of people will move into a new home and just hang thier art on all the existing hooks in the home. Which really doesn't work. I have to admit though, I've been guilty of it in the past - especially when I was renting.
Now there are some great picture hanging products available from 3M - so there is no excuse not to hang your art and have some fun with it. Unless of course it weighs a ton - then I suggest you bring out the big guns - cordless drills and someone who knows how to use one!!
Here's some great images of artwork displayed in a variety of ways. I think its a matter of having a bit of fun with it - don't take it too seriously. Mix and match, hang unexpected pieces in unexpected places and go bold!!
