The pattern was also a bit of a pain, with all the knit stitches knit through the back loop and a constantly shifting of the pattern from row to row.
But I am very pleased with the end result. The single skein of yarn had more than enough yarn for this pair of mittens, and I wish I had made the cuff a half inch longer (I made the hand shorter than recommended. They are extremely lightweight, the yarn fluffed up nicely as I knit, and I think they will be warm for their weight.
The yarn comes from Great Northern Yarns and the pattern is also theirs. Their customer service is exceptional. I ordered the yarn without the pattern and later saw the "kit" offer and I emailed them to ask if I could get the pattern. They sent it out immediately by US mail and I had it in 2 days.
