This is easy to make considering I am just a beginner at sewing myself and never even made a template before.
I do not have a template to give to you... but its easy to make. I will try my best to work with you guys step-by-step. If you have any questions just leave a comment below or contact me on my Kik (username : temotokarii) and i will try my best to work with you as i said before.
Now lets make a zombie ^^
Step 1: Cutting out the pattern
First create two twin circles ( about the size of your fist or palm ) and in one of the copies you made, cut a small hole (i used the size of my thread wheel thingy to measure this) in the top corner on either side (depending on the side you want it, this will be the bulging eye)
Then make another circle a little bit bigger than the eye hole you made, so the eye will bulge out.
Next just cut out a little cloud like shape out of any size you want, should be smaller than the head though.
