That’s a very interesting (and involved) process. How many feet of cording do you think you’ll end up using for the entire bench?

Have you ever heard of a singer-songwriter named Laura Veirs? She has an album titled Warp and Weft. I didn’t know those terms before I bought the album. It’s funny where one learns things.
Ron - I have that Laura Veirs album.  In fact, I'm going to play it on my computer as I respond here.  

I have been keeping track of arm spans lengths of cord I've been using, so I should be able to calculate a reasonable estimate of the total length when I'm done.
