So, this one might just do the trick. I bought a book with this pattern for a envelope card probably 5 years ago - maybe more! That's how long I've been wanting to give it a try. I finally sat down, copied the pattern, and voila! It's really pretty easy and its so unique that it really makes an impression.

Here are some tricks I learned along the way...
I used a long strip of masking tape to mark one of the grooves on the scor pal...it made it easier not to accidently skip a groove and get on the wrong track when I was scoring a long section.
Another important tip. Don't line up the edge of the paper with the edge of the groove. Instead, center the edge of the paper in the center of the groove - this ensures that your score line lays properly for the fold, otherwise it's too far out. I hope that makes sense!
I also discovered (yup, it took me a few steps to get here!) that I could lay and tape all the layers down and then just cut them all at once with my nestabilities...it need a little snip in the two corners with scissors because 3 layers is pushing it but it worked!
