I did not really do anything special to shape them. I cut the cork at an angle to make two popper heads then I did a little sanding. I cut an angled slit in the bottom and super glued the hook in place. I then used an xacto knife to cut a cup in the face. I took the cork that I carved out of the face chopped it up and used it to file in the slit in the bottom, sanded the bottom and primed, then painted. It was a simple operation, but these poppers are huge because the corks swell as they dry.
