See HUGE raglan underarms HUGE! What do I have that much underarm flab.
Look at that extra back fabric!!!
That about sums it up.
This yarn also doesn't have enough twist to give body. The alpaca gives it too much drape and its a bitch. So this will get pulled out AGAIN, and maybe one day it will become a blanket, a nice soft cozy blanket, not a terrible sweater.
