For a waterfall card you will need
8 x 5cm square images
8 x 5.5 cm squares for backing
One A4 sheet of card for the main card
1 x 5cm by 15cm strip of card
1 length of A4 x 5.5cm
I chose some butterfly printed paper which had arrived in the post to make the inside pocket (for my handmade envelope and personal greeting) and the edging on my card. The pull, decorated with another butterfly, is just a folded length of patterned paper. When you pull on the end, the squares move backwards until the last square image is seen. Then you can push the strip upwards and the squares return. I hope my husband likes it.
