We are close to Halloween now and a lot of people are making wonderful pumpkins and jack-o'-lanterns for the season.
I will not go into a full tutorial as you can find quite a few good ones out there. I though I would just note a few thoughts.
While there are a few methods of using air dry clay and polymer clay the main two will be using tin foil or a marble.
The tinfoil method involves lightly crumpling tinfoil into a ball or oval, you can also use a corkscrew so that it is easier to remove the foil after baking.
The tinfoil method is better for making oblong shapes and this way you can create a solid pumpkin without having to glue two sides.
I still prefer the marble method myself. I think searching out different shaped glass marbles next year will be my style.
A large medium or small marble is covered with a thin layer of clay.
In this shot I, I am using a thin layer of glow in the dark clay first then covering that with the orange clay.
When doing your "carving" you may prefer to indent your face first if you have trouble with symmetry or position.
But basically this method is the same, cut your face out, line a perfect circle around the entire marble and then after you bake you will remove off the marble and glue the two sides back together.
A little paint along the lines and edges to give it more depth.
These few here are just some quick scraps but you can see they are all hallow and decently sturdy.
You can add your little flickering lights to them.
Or as I did with a thin layer of glow clay, have them smile in the dark at you;P
I encourage you all to try making your own jack-o'-lanterns with these simple methods.
Now time to be embarrassed for eternity!
...here you go NSA... and time to feed the trolls... enjoy :P
