But I come to find out.... this is hard! And scarves don't even need shaping. I figured that, given my not insignificant experience knitting lace, this should be a breeze. But, uh, it's not. The rules of the contest specify that the pattern must not be published prior to the contest, so you don't get to see photos of the design I finally settled on, but I am going to show you the rejects.
(Washed out with flash - makes it easier to see the pattern.) The bottom design is the first try. But in addition to being fiddly to knit, it's pretty complicated and hard to see in a scarf. I like it a lot, though, and think it's got potential. Just not for this project. The design on top... eh.. not so much. It's simpler than the bottom, but still not hitting any notes.
Attempt number three: Something still not hitting right about this one. Subtle, but to the point where it gets kind of hard to see.
So what did I end up going with? Well... that remains to be seen. I'll post photos, and the pattern, after the contest is over. Early August.
