This week's Tutorial Time challenge on Speedy TV is the Never-Ending Card, a technique I learned a couple of years ago. It is much like a puzzle -- you keep turning it and get a different look each time. In Pat's tutorial, she said that you should pick a theme for your card. My theme is a Birthday Butterfly Garden. I looked through all of my MFP,aHC stamps and picked out about ten different flower and/or butterfly sets for my images.
The front looks much like a gatefold card; but, when you open it -- look what you get.
Now, you open it horizontally rather than vertically, and this is what it looks like. It's even a different shape.
It's now a variation of a gatefold card because you open it from the center and get this.
Open it again, and you're back at the beginning.
And, BTW, it looks a lot more complicated to make than it really is. Why don't you try one, here's the tutorial.
