I had so much fun 
water marbling Christmas ornaments last year, I decided to do it again this year.  This time around I made a heart pattern and used a variety of colors.  I love this craft because it uses everything I already have at home, and its cheap, if I mess up I can simply use nail polish remover and remove the pattern.

| I used Orly French White, OPI Party in My Cabana, Wet n Wild I Need a Refresh Mint, and  Sally Hansen Lovely Lilac. |

| You can use a clear ornament or an opaque one.  I like the clear ones because you can see the design through different angles. |

| I water marbled my mails also.  You can also see that tutorial in the videos below. |
