Once you have sewn or bought everything you need for your Santa. You then make a easy to do PVC frame for him..Cost about $15.00 to do this for a full size Santa for the yard: or less if you are making it for your car.You would only need from the waist up.

You then can make the body out of large yard bags fulled with crumpled newspaper and then duct tape it to his PVC frame.Or you Can buy some chicken wire and duct tape and make a light weight body that way. And for the yard you will need 3' long rebar found at the hardware store like Lowe's or Home Depot. you hammer the rebar in the ground and slide the pvc frame down over it to hold him up.
I will give you a link so you can see what I'm talking about: The body you see In the pic's I used to make a Grave Digger for my yard. But The process is the same.. I change the bubble wrap to black tubing.
