Bye Bye Bell Sleeves
Step 1: Determine how big you want the arm opening. You can figure this out by measuring the circumference of your arm where the end of the sleeve is on your arm. Then divide this number in half to determine how big the sleeve opening should be. If the fabric has some stretch, you’re golden. If the fabric doesn’t have any stretch, you may want to add 1/2″ – 1″ just so it’s not cutting off the circulation of your arm. This is your preference.
