Petal Wrap Bell Sleeve Pattern:

A: Length from elbow to first knuckles of the hand.

B: Length from elbow to longest desired point. In my case, 28 inches. This is also the straight of the grain and the seamline for each sleeve half to be joined. If this longest, heaviest section is cut on the bias, your entire sleeve will stretch.

C: Distance around arm just above the elbow, plus 4 inches.

D: Mark to match up sleeve halves when you wrap them around an arm.

Note: the point where arrows A, B, and C meet should sit just above your elbow. This will help keep the whole thing straight. Cut 4 of outer fabric, and 4 of lining. Sack line the entire curved edge, turn inside out, and press.
