If you want to come up with a cool paint design for a sign or anything really, then you might want to check out this water marbling technique. By just dropping paint in water and wiggling the paint around, shaping it just so, you've got a great paint dip! It creates a stunning and colorful pattern that looks fantastic on pretty much anything!
For more painting techniques, we go to Michaels Stores. What's great about this method is that it doesn't require a brush at all. With just a few tiny chains and some drops of paint, you can create unique flower-like patterns. That's all there is to it; just pull the chains across the paint and you're an artist!
