Two or three pom-poms down the front of the costume help convey a clown costume. These can be done with fabric that is left over from your ruffles.
Cut a length of fabric strip, half the width of what you cut for your ruffle. Finish one edge of the strip the same way you finished the edge of the ruffle. Use a gathering method on the un-finished edge of the strip. Gather the strip of fabric. Turn in the raw end on the strip. Roll the gathered strip to form a flower or pom-pom. Use a hand sewing needle to sew through the rolled up fabric at the gathered edge. Sew and secure the rolled up layers. Hand baste the pom-pom to the belly of the sweat suit or pajamas, remembering to start spacing them below the neck ruffle. Clown Costume Spots - A solid color sweat suit or pajamas can be transformed even more by either hand basting or using fusible web to attach round spots randomly on the clothing. Using fusible web will be pretty permanent which will probably make the pajamas a favorite pair but may stop the use of a sweat suit so use your discretion for attaching spots.
