Place the sleeve in the armhole of the waist with the under-arm seam about 2 1/4" to 2 1/2" from the under-arm seam of the waist. See that the seam of the sleeve hangs straight to the front of the wrist and that the top of the sleeve hangs straight to the back of the hand when the arm is dropped straight down at the side. Pin the sleeve in the armhole, being careful that neither the waist nor the sleeve draws in any place when the arm is raised or lowered. Bend the elbow and see that there is sufficient room to do this without straining the seam of the sleeve at that point. Pin the sleeve up at the bottom to make it the desired length. A sleeve should fit easy on the arm, otherwise it will be uncomfortable and will be likely to pull out at the seams.
