I first saw this card made by Mary Fish. She used Note Cards and Envelopes from the catalog
(pg 160, twenty 3 1/2x 5" cards with envelopes for $5.95). She added a white layer and punched out the elegant butterfly then added dsp behind the butterfly and added a white punched bitty butterfly such as you see here. Aislinn Chapotelle added the idea of using embossing folders to the white layer. I added the colored layer between the white and the card and made mine full sized cards. Most I left blank so the sentiment can be added when needed. This card would work well for birthday, get well, thinking of you, thank you, even sympathy!
This dsp is from a hostess pack from last year. It is a great way to use up scraps. I turned my embossed layer upside down to punch the butterfly on the opposite side of this card. Just had to play a bit.
