armholes not flexible enough
I notice that every baby sweater I make, the armholes are not stretchy like the rest of the sweater. I suspect I am pulling the seaming yarn too tightly when I sew in the sleeves, but it seems to happen whether I inset the sleeve before or after sewing the side seam of the sweater. And I have been trying to sew in the sleeve more loosely. Still they are tight.
Any advice to help with this problem?
