The second piece, is also Always Artichoke and it is 6 1/4 x 5 1/2, score at 2".
This second piece gets glued to the front panel with the 2" piece sticking out towards the middle panel of piece 1. (Are you with me so far?) I left it open a little so you could see where it is glued together. That front piece with 2 layers is now the FRONT of your card. The little 2" piece will be the little slider that moves when you open the card. 
Here is a top view of how the card should be put together so it slides properly...the 2" piece will go between panel 2 & 3, so when you open the card, the 2" piece will slide in front of the middle panel hole.
IF anyone tries this, please let me know how the directions are, if I forgot anything, or if something is confusing! I didn't have a tutorial to follow, just the sample, which made it easier! Post a comment with a link to your card if you make one!! It is a really cool card, I love how it slides!!!
I hope you enjoyed my first photo tutorial & I hope it made sense!!!! Have fun with this card - it is perfect for those "little" stamps!!! You could always adapt the size of hole too, or make it a square, oval, etc.
