babies, babies everywhere

I’ve got at least 3 babies to knit for in the coming months. My boss, who’s having her first kiddo, is beyond excited, and is due in April. I was thinking of making a baby blanket for this one.

I recently read The Golden Ratio, which is all about phi, or 1.61803399 . . . It’s a number very closely tied to the Fibonacci sequence (you know, 1 1 2 3 5 8 13 21 . . .) And in the book there’s an image of a Fibonacci rectangle—which could be used to make the Fibonacci spiral, which is also a golden section. (Confusing, I know, but look:)

Fibonacci Spiral

Ignore the spiral drawn on there. Note that each section is a square (with sides equal to Fibonacci numbers). Now wouldn’t this be a cool baby blanket, done with each square in a different color? I could work out my gauge to match the numbers in inches. Say that I wanted the largest size to be 34 inches (lopping off that 55 square)–that puts the short side at a little less than 3 feet and the length at about 4.5 feet. Which seems like a nice size for a baby blanket, right? This means 9 colors.

The other option I’m toying with, though it’s a lot more geeky and not as immediately visually pleasing, is this math problem of taking a rectangle and filling it completely with squares. Like this:

perfect rectangle

It’s apparently a difficult little puzzle that mathematicians like to entertain themselves with, and being historically a geek myself, I do find it pretty neat. But at a glance there doesn’t seem to be a specific order to it.

I think I’ve made my decision, but I’d love any input. My leaning is toward the Fibonacci spiral version, for one important reason: If I build my way up, starting with the 1×1 squares and going up in a spiral, I can always cast on by picking up stitches along one edge, rather than sewing all the blocks together at the end.

Speaking of which, are there special tricks for doing that (picking up stitches along an edge) without creating a totally ugly back? It may be that I’ll have to sew things together anyway.

    Hey! I read that book! I like the Fibonacci rectangle for the blanket. The Crayon might be an excellent yarn choice — are you thinking of using it?

    I like the Fibonacci idea too. Me myself being slightly geeky (I designed a tote bag -still unfinished btw- using the aurean number -however it’s called in English-). So yes, I’d go for it. Have you realized any square only touches four other squares, and you could make it using only five colours! And each square would only touch different colours *grin*

    Yeah, you have to go for the golden ratio — much more soothing and pleasing to a baby than chaotic squares — at least according to all the cool theories about the ways the golden ratio is pleasing to human perception. (In fact, I’m sure the baby doesn’t care, but I still think it’s a cool idea and the best choice.)

    By the way, have you considered doing intarsia? No seamed edge (or stitches-picked-up) edge that way, and it would be a REALLY easy intarsia to do.

    Oh, if it helps, the baby blanket I made was 30″ by 30″ (I think) and used six balls of Crayon (I think) on size 6 needles (I think) in garter stitch (I’m sure).
