The Matchbook I posted a few days ago got some attention and after some requests for measurements I finally went and figured it all out again so I could share:
First, the width of the piece is 3.25"
Now, measurements from the top (front flap) to the bottom (staple flap) are:
3.25", .25"" (binding if your notepad is .25" thick), 3.75", .75"
The next layer (the cool carribbean layer in my sample) is 3" x 2.75"
The Amethyst layer is 2.75" x 2.5"
If you need further measurements, please email me and let me know. That should get you started, though.
