take a small handfull of clay about 1/3 cup and roll flat between two pieces of plastic wrap.(I found that the plastic food bagsare better for this as they don't bunch up. use two one on each side)
Once they are about 1/3 to 1/4 inch thick and between 4-5 inches long, then take off the top layer and carve a rounded top of the door,
Straighten out the bottom and sides by cutting off excess.
Take a small slice off the black polimer clay and slive four pieces about twice the size of a pencil lead and as long as the clay is wide.
Put three on as binders to hold the door on
Roll the forth one into a door knob, and put on place by pushing down on it to secure
Now that the hard ware is in place use the cuticle stick to make lines in the door like a tree. then put scratchsand nicks in it to make it look like a wood door.
using a tooth pick push a hole through the place where you want the knocker to go.
Now you can either use the other piece of the toggle as a door knob turn like in the picture above or not like the picture below. If you use it install it now by pushing the heart part into the black knob.
Then fire as directions call for in oven.
Spray or varnish being careful not to close off the hole for the knocker. You can insure this by leaving the tooth pick in while firing and varnishing. But keep turning it.
Take some wire or string and attach the knocker through the whole and secure on the other side with knots.
Secure to your tree or house by either glueing, attaching to a stick that you put into the ground, or using leather straps where you put the black polimer.
