I wasn't sure what type of greeting to use so I went with "Best Wishes" from Petite Pairs. I thought this greeting was appropriate as a "farewell" greeting.
The background is a mix of stamps, both Off the Grid and Gorgeous Grunge. For the colors I decided to use Summer Starfruit, Island Indigo and Early Espresso.
