We had a 75th birthday surprise party for my mom. She was clueless. It went off without a hitch. The theme was black and white and pink. For the invites I used the pun "Don't let the cat out of the bag".
I used the Kitty from Cindy Loo and like how she turned out. She reminds me of the kitty from Pepe Le Pew. The envelope was made from Tags Bags and Boxes and More.
