I’ve used this technique (Fibonacci Sequence) when crocheting scarves. It’s fun and a great way to use up odds-n-ends.
Fibonacci was an Italian, one who came up with a particular kind of mathematical sequence. A Fibonacci sequence starts with two numbers. The third number is the sum of those two numbers. The fourth number is the sum of the previous two numbers. Repeat forever to build a sequence. The Fibonacci sequence that youre most likely to come across is this one:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, etc.
Why am I telling you this? Because playing with Fibonacci sequences and making Fibonacci stripes is knitting for your inner math geek.
