I got a card like this for a swap at Leadership in January and didn't think much of it until I opened it up and thought WOW! Cool little popup- The card did not have anything in it to identify whose card it was- I took it apart to figure out how it worked and I wrote it up for whoever wants to make it- If you know whose idea this is, PLEASE let me know so I can give credit to the cardmaker.... this is so clever!
Take a cardstock 4 1/4x 11 and score it 2 1/4, then at 7 1/2 inches along the long side. scallop punch the short side on the left and emboss with square lattice folder or some other folder of your choice up to the first score line as shown.
Take a piece of 1 1/2x 4 3/4 strip of CS and score it at 3/4 inches.
Take a triple flower punch and punch 3 different colors to make the bows. Attach one for the center bow centering it on the score line using sticky strip on the short scored side only as shown and then again on top of that. The right side should not go over the score line on the right (see first picture). This is the pop-up mechanism.
It should look like this when the fold is open.
Take 3 - 1 1/4 inch squares of coordinating DSP and little strips of cardstock and the triple punched flowers and adhere as shown. Make sure you put tape only on the middle mechanism and not on the whole back so it will glide back and forth well.
Add more sticky tape as shown and attach a 2x3 inch piece of carstock with your sentiment ( or gift card or picture or ....whatever you want to pop up!)
Be sure to stamp the sentiment before you stick it on to ensure a clean stamped image. Then sticky strip the front sides up to hide the mechanism and let it slide!
