I was doing quite well with knitting both sleeves at once but then I realized I forgot the increases.  Then I got the yarn tangled up.   Eventually I decided that while this is a brilliant idea I currently don’t have enough spare brain cells to accomplish this task.

My main concern with knitting them separately (other than time) was that lately we have calm days and high stress days.  If one sleeve is knitted on a calm day and the other on a high stress day then one will come to my wrist and the other to my elbow.  If this happens, I’ll just have to deal with it.
