Easy Wall Art!

I really really want to do this.  She made these using those decorative rubber door mats.  "She" being the lady that runs "Frugal Home Ideas"...a blog about...you guessed it, frugal home ideas.  Click HERE to get the full details of how she did it.

Here's my problems:

1. I don't know where in my house I'd put something like this
2. It's winter and I hear spray painting in the cold is not good
3. I don't have a rubber doormat and don't want to buy one because I'm even more frugal than this lady.  If you have one you don't want anymore...let me know.
