I just love the Sail Away stamp from SU.
I made a card similar to this in black and white, you can check that here. I decided to make one using my fave pool party DP...I can't help myself. I grab that color every other card I make!
The sentiment is from Lizzie Anne and the bakers twine from My Minds Eye. I didn't add a button like I did on the black card, as I want to be able to mail it.
