To make a cape prepare a small circle and cut along one of the folds.

Fold the ends of the cape to the inside.

See if there is a design element you want to incorporate. I folded along the edge of this design.

Wrap the cape around the doll’s neck with the opening in the front. With a small piece of tape with the sticky side facing toward you slide it under the cape and press to both of the cape’s edges to hold the two sides together.
