Wanting to get practice using software for future projects, I started with this simple form:
I used 123D Design and 123D Make for the sphere. Then I imported the cut file to Silhouette Design and added the ears. This was cut from chipboard (<1mm thick).
I am happy with the results. I want to make this out of wood, and include a base for it to sit on. Or, they could turn into Christmas tree ornaments.
