As each year my kids had carnival parties at their places and they needed a costume.
My son is having his 'Star Wars phase' since a few months and wanted to become the emperor. I pieced a cape on base of Burda pattern #2494 Style C, but I enlarged the hood.
My daughter became a princess again, because the dress still fits her. I pieced a pink cape (Burda #2494 again) that she also has a new part on her costume.
