I must say very resourceful! I don't have contacts but still a great idea!
Ummm...remind me to never eat any baked goods in your house. "Mmmmm this muffin is tasteee...bleh...ahhhh...is that a contact lense I'm chewing on?"
Haha. So innovative. If I stay at someone's house and forget my contact case, I usually use shot glasses. Because I'm klassy.
