A simple Thank You card using the Best Birds stamp set from Stampin Up.   To create the background sun and sky - you create a mask to cover the sun and sky areas so you don't overlap the colors when you are sponging the ink.   

The Thinking of You card used the same masking technique.   But was stamped with the tree from Thoughts & Prayers stamp set.  The tree shape was double stamped to add some additional branches (the tree trunk was masked for the second stamping).  For additional interest we added a bunny image that we found on Google images and die cut it on my Cricut Explore Air.
