Pillow Case is found sort of right-middle on the Pillow Wall, a pair of cracks in a left-facing corner system. I think most people usually start out in, and mostly climb the right crack, that starts as tight hands, and gradually widens out to fists as you approach the rim.
Cams from #.50 Camalot to #4 Camalot, assuming you pro in the right crack only.
