So I have a love/hate relationship with water marbling. Sometimes it comes out AMAZING and others are just awful...
I'm not really happy with this one...something about the blue/orange I used made weird colors and the polish wasn't cooperating with the patterns I wanted. However, the actual marbling turned out well, with no missed spots or water bubbles so I can't complain too much.
Go check out some great marbling by other participating bloggers!
