I fixed a hole in a cape from a broadhead. The hole was in the white throat patch. It was a pain but it just looked like a scar when I was done. I also just took a deer in with a 12 ga slug that was put in the neck at about 6" from the ear. I will have to cut the hole about 3 times the size of the slug hole to repair it but it is repairable. I am more worried about the shoulder/brisket area blown to bits from the initial shot. I am keeping my fingers crossed the form doesn't have the full of a shoulder and misses this spot. But back to your initial questions those holes should be an easy fix. Good Luck.
