Never Ending Card

"I am on The HUNT for the Best Never Ending Card Directions " on the Net tonight

It's a project for the kids...

Here's what I have so far...

This video...PLUS, I found these...

Home and Garden Television

Victorian Originals

Is that all there is???

What I really want to see is an image of how it all works (not only how it's made).

Do you know of any others...???
