I am hoping to make a car seat cover, or three, for our trip away.

Anyone have any suggestions?

I was just going to make something simple, something which looked a little like a fitted sheet, with gaps for the straps obviously. What do think? Does that sound right? Or do I really need to use a pattern?

Oh, and what kind of fabric? I just want something that keeps food crumbs from the inside of the car seat as its not the easiest to get off... but i also wondered... if she got sick, or had a leak... it'd be good if it was thicker and possibley waterproof...

Give me some suggestions, I'm not sure? The only ones i have found at stores are $50! Not paying that much!
