I recently purchased a Sizzix Circle Flip-its die. This die makes flip-it cards so easily! My brother-in-law and his wife are celebrating their anniversary in May, so I used the die to make them a card. The card flips around "in a circle" with a space for the message on the other side.
In order not to have to cut any designer paper, I found the "Four Seasons" stack by DCWV on sale at AC Moore. These papers are perfect for the flip card as they are printed on card stock--heavy enough to not require another sheet of card stock as the base.
I entered this card in the following challenges: Creative Moments--Challenge 17--Circles and Crafty Creations Challenges #222--KISS.
