Here is one alternative -- buy a costume and stuff it. You could stuff it with old cloths, etc
This site has a childs and an adult.
I ordered one for my front porch. I think the grandkids will like it. There are photos of the guy in it and a video. I will have to sew a zipper up the back , attach the head and sew some soles on the bottom to clse the legs. I can stuff it and after christmas remove and fold away. I am going to try the old cloths first maybe use some pillows.
