Check this out - I want to do this!!!

You HAVE to check this out - Leah Buechley has this website that is what I want to do!! That pompom on the top of her hat? It's not glow-in-the-dark yarn, it's an LED. Under one of those links on the left (there's a lot to explore) is the Electronic Sewing Kit (tm).

I got to have dinner with Joan Schrouder and Susan Moore at the Riverside Mission Inn tonight - what a blast!! Joan is teaching tomorrow for the Riverside Knitting Guild, and Susan is the coordinator. We had some fun brainstorming... but I think I left my brain in Riverside. Wish I could remember some of the great ideas!! LOL

hmmm.. random cogitations on Fibonacci

Marcy commented on Fibonacci sequences in knitting- go see Fuzzy Galore for more details. I've used Fibonacci many, many times, but it just now occurs to me that it's a binary system. In other words, there are two colors (or parts of the daisy or chambered Nautilis or whatever) that are going back and forth in the sequence.

What if you want to use THREE colors? Or (gasp) more? Methinks I need to consult a mathemetician. OK, yes. Wikipedia has an article on Fibonacci sequence ... but it makes my head hurt. (yeah, the sinuses again. I gotta admit that Sudafed sends me down some pretty amazing paths, while simultaneously making me incapable of higher reasoning. Strange, but there you go. Rather, there I go.)

Can somebody mathematical give me a SIMPLE formula for a 3-color Fibonacci sequence?

hmm - maybe I could just go from this (where A is the first color, and B is the second)

A1, B1, A3, B5, A8, etc

to having colors A, B and C do this:

A1, B1, C3, A5, B8, C13, etc.

It's boring (and not fun to count) to have knitted stripes of more than 5 or 8 rows. I wish I could remember (and thank!) whoever told me that you can go up and down the sequence, as long as you don't skip numbers.

In other words, 1, 1, 3, 5, 3, 5, 3, 1, 3, 1 etc. Don't go from 5 to 1, or 8 to 3.

I ought to sit down and try this with 3 colors!!
