I have absolutely no idea if the pattern I just doodled up (shown below) is going to work.
I made some blind and totally unswatched assumptions about gauge, took inspiration (but not stitch counts) from the Hello Yarn generic Norwegian Mitten template, and ran with it. I’ve used my dragonfly pattern posted here before, plus idle chicken scratches.
I suppose the next step is to see if I can get about 7.5 spi, figure out which colors I want to use, and try to knit this totally untested pattern.
Heck. Risk can be fun if taken in small doses.
UPDATE: Please don’t try knitting from this graph yet. The JPG filter appears to have cut off a column of stitches (there are 64, not 63 on the cast-on row). I’ll repost a final, corrected graph when I’m further into the project. For the time being, I can report that gauge is working out o.k. for the corrugated two-tone ribbing (two inches, done before row 1 of the chart), using my lofty ancient Britania Shetland on 2.5mm needles. Dense pack, but good for a nice, wind-proof and cushy mitten.
Note that the two-tone ribbing curls up a bit. That’s normal. Corrugated ribbing is not as curl-proof as regular K1, P1 ribbing.
String-Or-Nothing 
The patter looks very nice! I can’t wait to see it knit up.
