This is a great masculine stamp set that's just made for watercoloring. The colors in the first one are Baja Breeze, Soft Suede, Riding Hood Red and Bashful Blue. The birthday greeting is from On Your Birthday.
The second one also uses Inspired by Nature for the grass. The blue layer was crumpled up and then flattened out. Then I used the mahogany ink from the Distressing Essentials kit to highlight the wrinkles (kind of opposite what I do for my face!).
