As someone who designs a lot with BP, I use grids pretty frequently. So I was wondering what's the best technique to use for pleating.
I've tried several, and they all begin with folding x/2 grid and turning the paper over.

- Pleat from the center outward, stacking several pleats
- Pleat partially (1/2) before unfolding and doing the other direction
- Spiral around the paper, working outward and doing one pleat at a time

So which one of these methods is the most efficient?

There's some discussion of that here: viewtopic.php?f=12&t=10191

I use boxpleating a lot so I fold a lot of grids. The way I precrease a grid is as follows...
I fold half the grid alternating between horizontally and vertically and then turn the paper over and fold the other half alternating between horizontally and vertically. For example: if I want a grid of 32 I...
Fold in half horizontally then in half vertically. Then I fold into quarters horizontally then quarters vertically. Then eights horizontally and eights vertically. Then sixteenths horizontally and sixteenths vertically. Then I turn the paper over and fold into thirtytwos horizontally and then thirtytwos vertically. This way I have a grid of 32 and the creases are already alternating between mountains and valleys which makes collapsing easier. I found that alternating between horizontal and vertical creases is more accurate than folding all the horizontal crease and them all the vertical creases. I hope this makes sense and isn't a complete confusion!
Also if you want to know how to divide a piece of paper into any number of divisions (3rds, 5ths, 7ths, 11ths, 13ths, 17ths etc...) check this link: http://www.flickr.com/photos/langko/781 ... hotostream
Hope this helps you
