Take out your watercolors and play!
Watercolor designed paper is everywhere and it's so pretty! Why not try to make your own. You choose the color and what to paint, the result, your very own design paper!
I had used Heidi Shine on some and the watercolors I used are the White Nights by S:t Petersburg. These are really good value and I highly recommend them. How ever you can use any type of watercolors, the important thing here is to have fun!
