Back to the project in hand. I’m up to adding the edging to the Print o’ the Wave scarf, which in part sparked the past two days’ digression into general edge-affixing techniques.
I am sad to say I have errata for the pattern as available now. I wrote to the author over the weekend to report it. While the mistake is not something that will trip up people who are comfortable with lace construction, people doing this scarf as a first or second lace project will be a bit more frustrated.
In Chart B – the graph for the edging, the next to last stitch box on rows 9, 11, 13, and 15 should be a K2tog, not a plain knit.
A good way to “proof” graphed lace patterns is described in the Lewis Knitting Lace Book published by Taunton. It’s in several others, too but I think Lewis outlined it the most clearly. To paraphrase, special techniques and weird row-perturbers aside,, for most simple lace to remain at a constant width, with left and right edges parallel, the number of stitches increased must equal the number of stitches decreased. For lace to grow wider, there must be more increases than decreases. Conversely, for lace to narrow, there must be more decreases than increases.
On the edging in question, we know that rows 9, 11, 13, and 15 are the ones on which the pattern narrows, forming the “downhill” side of each repeat’s gentle pyramid point. But if you count up the increases and decreases on (for example) row 9, you end up with four stitches added (all YO increases), and four stitches decremented (two k2tog, and one k3tog double decrease); yet the pattern shows a net one-stitch loss on each odd numbered row. Since the visual lines established in the design are very strong, there’s only one logical place where that extra stitch can be lost – the next to last position on the row.
I have to admit that I was a bit tired when I first played with the edging pattern and kept messing up. But I muddled through, and then compared this variant of the Ocean edging to those in my other reference books (most notably the most excellent Heirloom Knitting by Sharon Miller). Those patterns do put an additional decrease in the penultimate position on each “downhill” row, so my guess has precedent.
I also have to moan about another minor lace tragedy, visible in the photo below:
All that muddling about at the beginning, starting the trim and ripping it back resulted in a dropped stitch over near the beginning of the edging (I’m working along the top edge of the stole first). Aaargh! I don’t want to rip back, so I’ll have to repair it tonight.
