The right fit

Hello knitters-

Today's topic is how to make things fit.  I saw this on Knitting Daily and thought to pass it along.

Well I am trying to fix a project that I had knitted.  I made this sweater for my mother and the sleeves ended up being too wide.  I am trying to figure out how to fix it.  I think I am going to have to cut and sew it on the sewing machine.  Any thoughts or suggestions?
