A regular triangle scarf or shawl, knitted from the top centre out is much easier to design. Here's why. The edges of such a triangle grow symmetrically. Have a look at this stunning example. See how each side of each triangle grows at the rate of one new stitch every right side row? In a crescent scarf, like my Fibonacci, the inner edge grows as above at the rate of one new stitch every right side row,
BUT the outer edge grows much faster, at the rate of two new stitches every right side row.
Therefore, the pattern stitch cannot grow on each side in any sort of symmetrical fashion. This is OK if you're dealing with a simple horizontal pattern, as in Fibonacci. It makes for much trickier planning if you're thinking about doing lace. That's what I'm doing. Is it worth the trouble? Definitely.
P.S. I almost forgot to show this.
It's my new birdbath, from the metalsmiths in Merrickville.
P.P.S. For a reader who asked (via Ravelry) to see what the new shoulders in the Wheatsheaves cardigan look like.
It's hard to get a photo of shoulders when no one is in the sweater! But, I think you can see how nice and smooth the shoulder area is now, with no seam to get in the way and the short row shaping doing all the things it's supposed to do.
