After watching several different tutorials on YouTube (the best I found was on 'Dawn's Stamping Thoughts') I made a few tweaks and came up with this list of instructions for myself, I then did it all again adding pictures to each instruction.
This will probably be a long post but that is due to the number of pictures and not because it is difficult to make a Waterfall Card.
The first thing to do is to cut the pieces of card you will need to create the Waterfall.
Centre and stick the narrow strip of Dark Green Card to this tape.
This will create the 'edge' for your Waterfall to flow over.
Introduce the Waterfall to your Card blank, and decided where you want the Waterfall to be positioned.
To operate the Waterfall you need to pull on the back tab (the light green card you can see at the bottom of the waterfall) so this needs to either have a tail for people to pull or it needs to be at the bottom of the card.
Using either brads or eyelets secure the Waterfall to the Card using the wings either side of the Waterfall 'edge'.
This one uses Prima Flowers & Gems in place of the stamped images and I punched a whole and added some wool to the bottom tab to allow you to pull the Waterfall steps over the edge.
