Here is a fun idea: go to a store near you with a large wine section – like World Market or Total Wine. Wine labels are a great source of design inspiration, and are usually arranged in easy to peruse store aisles.
Using a discreet camera (like, say, an iPhone 4), take pictures of any label that catches your eye or pleases you in some way. Don’t overthink it – go with your gut. Do you like it?
Later, review all of those photos and use them for inspiration. Another thing this can do is reveal to you what design tendencies you may have.
If you visit my new Flickr set, you’ll see what happened when I did just this.
What I found out about myself is that I seem to like warm colors combined with strong black line art.
What would a test like this do for you?
