Say you have an empty wall and an empty wallet. Luckily, there is a very simple solution to your problem: free paint chips!
These little cards can be found in the paint section of any decent hardware store. Just walk in and grab a variety of colors. The only other things you need are a pair of scissors, painters tape, and some creativity.
I got the idea stopping by a house where people had taped a bunch of chips to the wall in a much more abstract pattern, so credit goes to them, whoever they are. Also, after writing this up, I realized there is a similar instructable here
, but I figure that this is different enough to get its own.
This is a great way to make a space your own, especially if you are in an apartment or dormitory where they get grumpy about thumbtacks and screws. I know when I lived in a dorm, blue painters tape was the only
thing allowed. Also, the irony of decorating with paint samples is enjoyable in its own right.
