About paths

Hey! I just got a trial version of Photoshop CS3 and I haven’t had any experience with Photoshop before, so forgive me if this question is stupid.

I was drawing a path, and then I modified it with a border of about 5 pixels. When I filled it in with a solid color, it appeared to be feathered. I checked in a lot of settings and set every “feather” option to 0 pixels, yet it still appeared to have feathered edges. Is there another way to fill paths that only fills the inside of the selected area without feathering the edges?
