I was going to mention that CASE is an acronym for copy and share everything.
I copy, period. It rarely comes out the same because I don't have the same stamp set or the same paper or I like a different color. I don't care if someone copies from me, period. For goodness sake, if I see a white card with a small group of flowers hand colored on the front ( a beautiful clean and simple) and I make a white card with a small group of flowers on the front is that stealing?
