Step 5: Sew hood to cape
Pin the hood to the gathered edge of the cape, right sides together, and sew. Be sure to keep your gathering even during the sewing process.
Once the hood is attached to the cape, fold the hood in half widthwise, right sides together, and pin along the top edge. Sew a straight line all the way across the top of the hood. At this point, you can decide if you want to sew a short line across the upper back corner of the hood to keep it from being pointed (see last photo).
