Many Creative Gifts -- "be thoughtful"

If you enjoy mathematics, then you're bound to enjoy crochet as well.  Sizing hats requires a little dividing and multiplying (check out my tip on hat sizing at http://www.crochet.lifetips.com/), but I just learned about a math concept that's great for creating striped patterns.  It's called the Fibonacci sequence, named after 13th century Italian mathematician Leonardo Fibonacci.  In his sequence, each number is the sum of the two preceding numbers, starting with 0 and 1. Thus, the sequence begins 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, etc.  Thus, if you want to make a scarf, for example, you can work in the sequence, using either rows or inches to create the striping in different colors.  How about a simple scarf with two colors, working 3 rows in Color A, 5 rows in Color B, 8 rows in Color A, 13 rows in Color B, and so on!
