Dayflower is a really pretty pattern in Barbara Walker's Second Treasury of Knitting Patterns, but it only has written directions. I was looking for a challenge for my charting skills and this one looked like a good one. It took me a while, but I figured it out. Here are some of the steps I used.

Charting 'Dayflower', originally uploaded by fuzzyjay.
Straightening out the lines that represent rows, with no regard to spacing of stitches:

Eventually I got to this point where I could arrange the stitches on a chart. The trick there was to figure out, based on the photo and the previous attempt, how to move the rows back and forth for best alignment of the stitch columns.:

Once I had the stitch columns aligned properly vertically, I could do the more-detailed stitch diagram. This one shows the path of the yarn through all the stitches, but not the actual over-and-under crossings of the yarn as the stitches are made. It's a bit sketchy because I only did one half of a repeat, then used Photoshop to flip and copy the repeats, and my Photoshop skills are not the best:

As I've said before, I'd rather figure out 5 ways to diagram a knitting pattern than knit it. I'm all about understanding the architecture...
