By all means, CALL TERRY! You too, Blaire, you both do amazing work!
The kite line is called Spider Line. I bought it years ago and I think it's made by the same folks at PowerPro. I got it in North Carolina for my kites but the shop is closed now. Catch the Wind in Oregon used to carry it, but I don't see it on their website. I got a 1,000 foot spool so I'll die before I use it up. It may be sold now for fishing line, but the packaging is different so I couldn't say which is the kind I have. I'm sure any synthetic would do.
Now that I have the pattern down, I can put the strand together in an afternoon.
