I figured out my lace issue!! Yay!
This is probably the most complex thing I have ever modified in knitting, so I feel pretty pleased with myself.
Here's part of what I've got so far, pinned out on the ironing board so you can see what's going on: ( Detail shot of my modifications )
I did a few repeats before noticing that the pattern as written
creates an odd sort of fork or misplaced bar on the lozenge shapes on either edge. Now, obviously, this could have just been my error in reading or executing the pattern, but it seemed unlikely to me that I would make the exact same error 6 times. I looked at the photos on the pattern page again, and I'm not positive, but it looks like that's the way the pattern is written.
Still, I didn't quite like the effect. I wanted the shapes on the edge to match the shapes in the interior. So I played around a bit. Mostly I just stared at the thing, then I stared at the chart, then repeated for a while. Someone suggested that I might be using the wrong decrease, and i thought that was it until I looked at it again. Eventually I realized that one yarn-over hole was too close to the edge, and that was happening on Row 7. Row 7 as written
was: Sl 1, K3, YO, ssk, K2, YO, *sk2p, YO, K2, YO, sk2p, YO, K2, YO* (rep * twice more), sk2p, YO, K2, K2tog, YO, K4. Mod #1
was scooting the YO/decrease on each side one stitch toward the center (so my new Row 7 read: Sl 1, K4, YO, ssk, K1, YO, *sk2p, YO, K2, YO, sk2p, YO, K2, YO* (rep * twice more), sk2p, YO, K1, K2tog, YO, K5.)
That put the YO in the right place, but the adjoining stitch still looked wonky. Then I realized I was overcomplicating it. Mod #2
was inverting the YO and decrease on each edge (so this Row 7 read: Sl 1, K3, ssk, YO, K2, YO, *sk2p, YO, K2, YO, sk2p, YO, K2, YO* (rep * twice more), sk2p, YO, K2, YO, K2tog, K4.)
That made it look just the way I wanted it! I figured this out by looking at the edges of the interior lozenge shapes on the chart and tracking where the YOs and decreases fell in relation to each other. I am still barely proficient in lace but I really feel like I learned something.
I'll be adding these notes to my Ravelry page, as well. I hope someone finds them useful!
Even though I've figued this out now, it is way too subtle to rip back (at least according to my standards) but I'm glad I can fix it going forward. I'm really enjoying knitting this!
