Cool! @CarryOnMyWaywardSons, I'm happy that I introduced you to a site you like!

Hi @Sherrysimmer I think I found the pictures you are talking about. The creator's site has been taken down but, I double checked and the links at Lana's CC Finds are still good: http://sssvitlans.tumblr.com/tagged/s4paintings/page/203

Please let me know if this isn't what you were looking for and I will try again.

Hi @iballisticbunny6 I can do that!
