How to Make a Cap-Style Sleeve
- 1). Measure around the top of the armscye of the dress or shirt you want to modify. Measure from a point level with your armpit, over the top of the armscye and down to a point level with your armpit on the other side.
- 2). Measure around your upper arm where the sleeve will fall, and add 2 inches.
- 3). Cut an elongated half circle using the armscye measurement for the curve and the arm measurement as the straight edge.
- 4). Hem the straight edge by folding it up twice and stitching it flat.
- 5). Turn the dress or shirt inside out
- 6). Pin the curve to your armscye, pattern side of the fabric facing outwards.
- 7). Sew the sleeve into the armscye.
- 8). Repeat the process for the other sleeve.
