Start with your fabric.
If your fabric has creases cut along them. If not make sure it is long.
Fold it in half and start sewing
Stop when there is only one side open
Fold it inside out and stuff it with the stuffing or fake snow.
Start sewing all the edges
Tie it off and you have your own pillow.
You can do it bigger or smaller. And you do another kind by not turning it inside out.
