Not enough yarn. Missing about 3 or 4 inches worth on each sleeve.
I think what I’m going to have to do is rip both sleeves out and start from the top. I think this sweater is just going to have to be content with 3/4 sleeves – something that goes to just below the elbow. That’ll leave me with a little extra yarn for seaming, and I think it will still look okay. I hope.
Sigh. More ripping. Grrr.
