I am fortunate to know several wonderful SU! demonstrators. Even more fortunate that they love to create and prepare fun classes for us to attend. I went to an event Sunday afternoon where we made 9 different cards. Gorgeous cards. I'm so happy I went.
So from what I understand most everything used on all 9 of these cards is from their annual Sale-a-bration catalog.
I must confess, even though this is not bright springy colors. This was my fave design of the day. Stunning.
