I made my Avatar at a workshop , so just followed the instructions we were given by the tutor. It is a folded layer star. I found one very similar in Gail Lawthers book "Fun and Fabulous Patchwork and Applique" and also Jennie Rayment has it in one of her books - forgive I don't the which one, she does lots of folded fabric designs.
As mine was for Christmas, I added the gold material which seemed to just set it off better.
