Here are some more pumpkins I have carved.
I am constantly looking for challenging patterns. My favorite last year was probably the dragon head. I don't really have any themes, just carve whatever I think in a cool pattern and that I think others might enjoy.
I have an Etsy shop which is where I get most of my custom order requests. Then I have to figure out what to carve, what to shade and what to leave from their pictures. It is challenging, but fun. I don't see how you can figure out what to cut out to make your great patterns. It always amazes me.
