First, I have to mention that I'm using Design Master spray paint. This product is great for making signs because of its blending ability. Unlike other spray paint on the market, it's translucent which allows you to layer several colors together.
You can achieve quite an impact with a few cans of spray paint and a little know-how! I hope this little tutorial helps you. If you have any questions or comments about it, please leave a comment and I will do my best to respond as quickly as I can. Thanks!
