The first time I saw this was on www.stamptv.com and it's worth watching since Gina's videos are always fantastic.
You can find her videos (part 1 and 2) here:
For those using A5 books, here are my dimensions for cutting & scoring:
Front and back DP: 8 1/4" x 5 1/2"
Spine: 8 1/4" x 2 1/8"
Score spine at 7/8" and 1 1/4"
If you want to wrap the spine further underneath the DP you can make it wider.
See Gina's videos (links on top) on how to put this together.
The stamped image is from GinaK Designs "Tree Silhouettes". The "Notas" I printed from Microsoft Powerpoint.
Ink used to stamp: Tim Holtz Distress Inks - Crushed Olive, Pine Needles
I'm entering this for the Scor-Pal Guest Designer call.
