This fun card uses the Baby Wipe Technique. You simply select 2-3 re-inkers (here I chose Pacific Point, Bashful Blue and Pumpkin Pie) and squirt some ink on a folded up wipe.
Using glossy white card stock, you drag the baby wipe repeatedly across to get the desired effect. Let it dry and stamp your images on top in Basic Gray ink.
Then finish your card! The "sun fun" comes from Life's a Breeze.
Oh, and there's another way to use this Baby Wipe Technique: Drop the colors of re-inkers next to each other on the baby wipe "pad" and, using a bold stamp, use the wipe as an ink pad, inking the stamp and then stamping it on your card stock.
