Wings again

Hi everyone, (:
a few days ago I had worked on my Tinkerbell wings.
I took a few pictures to show you :)
I hope you can understand what i had made.

First I draw my wings on a piece of paper.

Than I cut it out and use it as a stencil.

So I copy it on my of polystyrol  sheet.

Than I saw it out with a coping saw.

Its really difficult and exhausting. :)
