I love this Pop Up Slider card! It is fun, fun to make! I found the tutorial for this card on Pinterest! Check out Anne Rostad's beautiful Slider cards here and it's a tutorial!
I followed Anne's directions except I didn't use a frame that was already cut out. I made my own frame but cutting a 4" x 6" piece of card stock or decorative paper and then cutting in from 3 sides about 3/4 inch. Instead of cutting the top at 3/4 inch - I scored it - not all the way across - just inside the frame area- See below. It creates a flap! Along the bottom of the flap- I made a score line at 1/2 inch in. You will fold this flap in half from that score line not the end of the flap- You can see how it works below.
