This is the swing card I designed for a project for my demonstrator team to make at our monthly meeting. Above is how it looks when standing up. When folded to place in an envelope, it looks like this:
When the recipient opens the card, the center section swings around so she can read the "inside":
When I flatten the card so you can see the front without its folds, it looks like this:
To make this card, you begin with a piece of 5-1/2"x6-3/4" Pretty in Pink cardstock (100459, $5.50 for 24 sheets). I decorated the top and bottom edges of both sides using Cupcakes wheel (113121, $6.50--a Stampin' Around Handle is needed, 102971, $3.95).
Next, you'll make a 1-1/4" score line 2-3/4 inches from each side, at the top and the bottom of the card. From each score line, cut a slit 1-3/8" long. Then connect those slits with another slit (this cut on each side should be 3 inches long). The best way to do this is to use the Paper Cutter (104152, $24.95) with the cutting and scoring blades (104154, $5.95). When you fan fold on the score lines, you will see how the center section swings back and forth.
Other items needed to complete this card are: Crazy for Cupcakes stamp set (111618, $23.95), Certainly Celery cardstock (105125, $5.50 for 24 sheets), Whisper White cardstock (100730, $7.50 for 40 sheets), Staz-on Jet Black ink pad (101406, $7.95), Stampin' Write markers ($3.25 each; Certainly Celery--105106; Pretty in Pink--100045; Real Red--100052), and 1/4" Grosgrain Ribbon (Certainly Celery--109031; Real Red--109034; 15-yard spools for $4.95 each).
