Open up the embroidery hoop and set your drapes inside. You’ll also want to position the hanging mechanism in the hoop. Tassels or ribbon will both work well.
Close up the hoop and tighten the tension to hold everything in place.
Apply some craft glue to the outside of the hoop, being careful to avoid getting any on the fabric.
Press the costume store crown into the craft glue on the edge of the hoop, centering the crown with the front center of the hoop. Set the hoop and crown on a table to dry for two to three hours before hanging the canopy.
