Soooo you are telling us that cooking isn't your "passion"!!
I looked everywhere I could think of with NO luck. (I didn't want to order it online) Actually what I did was cut LGMH (paint sample from Home Depot) and used the backing of the paint sample for my stencil. Then once the clay was ready I layed the stencil on top and used my exacto knife to cut out the Mickey head. I know.... I know.... sounds REALLY easy .... you know how long it took me to figure that out!
My poor family will definately agree that cooking is not my speciality!
I tried cutting around the LGMH with a purple scupley tool, but it came out very choppy and the edges were not smooth at all. It's not too bad for my first attempt at sculpey, but I would like to try more. Maybe an exacto knife would be better.
