Not much sewing. Mostly tacked the boa to the tshirt with big globs of hot glue.
the way it is put together is. I put a t-shirt over a turtle neck. I sewed the t-shirt bottom to the turtleneck bottom and then stuffed pilow filling inbetween. once done I glued 6 boa's to the t-shirt. (To help I put the costume on a 5 gal bucket before I glued it on)
