I finished these Meeting St. Mittens in record time: two weeks!
I used Berroco Sox yarn. I had read on Ravelry that this yarn is a bit thin for a sock yarn, and I would agree with that assessment, but it worked out fine for this pattern I made one major adjustment: It looked like the mittens might be too long for me, so I cast off with 24 stitches left and joined them with the kitchner stitch. I think they look better without such a pointy top.
There is something so addictive about this pattern. I have already started the next pair -- using a different yarn with different colors.
