Stamps: See D's "Leaves" (which I bought years ago and don't think are made any more)
On the Birthday Card I used a set from Local King Rubber Stamp: "Spring Time Die and Stamp" http://www.localkingrubberstamp.com/ They have a video out that tell you how to use the die to get the 3 D card also. In my Cuttlebug I used the AB&C Plates for Cutting, and AB&B Plates for Embossing for this set.
Butterflies were cut with Martha Stewart Butterfly Punch (using same inked watercolor paper).
Dies: Spellbinders Decorative Labels Eight; Spellbinders Labels Four Small
