The elbow dart control of a one-piece sleeve can be divided and shifted to the control seam of a two-piece sleeve.

1. Trace the sleeve sloper. Cut out the tracing and the dart.

Shift some of the dart control to the wrist to widen it (Fig. 81a).

2. Extend the elbow dart across the width of the sleeve (Fig.

81b). Fold it out.

Fasten temporarily

3. Draw a line dividing the sleeve in half from cap to elbow, from elbow to wrist (Fig. 81b).

4. Fold each side of the sleeve so the underarm seam touches the center line at the armhole and the wrist (Fig. 81c). Fasten with Scotch tape.

5. Locate new seam lines in the underarm section-l inch in from the fold at the arm stye, 3/4 inch at the elbow, and 1/2 inch at the wrist (Fig. 81c). Notch the seam lines. The underarm section is generally one-third of the total width of the sleeve. Adjust the above measurements accordingly.
