Cape: Two cuts, no sewing!
I cut a slit in the short closed seam of the pillow case for his head to go through. I cut up from the opening of the pillow case about two feet, so it would be open like a cape. I didn't cut all the way up so we wouldn't have to use ties or anything to fasten it. His shoulders fit nicely in the already sewn corners of the pillow case, but it looked a little boxy so I tucked them in behind his shoulders to make it look a little more rounded. So that was it! A cut for the head and a cut to open the pillow case part-way. Not professional looking, but it was good enough for him!
For the mask, we painted a Transformer mask with acrylic black paint. We happened to have an extra mask.
My son put on black sweats and turned his black t-shirt inside out because it had characters on it. Black Sunday shoes and black gloves made him feel official.
He danced around with a 'light saver' and I had to pretend fight him. It was so cute to watch him pretend to be Darth sneaking up on me.
My favorite part was when we were discussing different Star Wars characters. He said he liked, "Bobey Wan Fett" I love that name! I think he morphed Obi Wan Kenobi with Boba fett.
Ha ha, Bobey Wan Fett.
