You know it’s always tough to get a sleeve in the way the pattern directions say…and then you have nicks and bumps. Well, there is an easier way.
Step 1: Instead of putting sleeves in after you have sewn the shoulder seam and the side seam, sew the shoulder seam the same as usual. Then pin in the sleeve and sew. Sew up the side seam after the sleeve is in.
Step 2: Be sure to pull gently (and only a little) at the sleeve while you are sewing. This helps to smooth it out and limits the bumps and also limits the number of times you have to use the seam ripper.
Finish your shirt like usual.
