Here is the Rose Wonder Stamp Set and I used Wisteria Wonder as my main color to water-color the card.  If your new to water coloring, start of with a really light mix of water and ink.  I use my reinkers in a small plate, allowing me to mix it out to the side of dish and have enough to color the whole flower with the one color then mix some more in another spot that will enable me to put some extra toning on the petals.

Why not try it, it’s a lot of fun.
