I'm trying to make dolls and other baby sew crafts and when I read the directions on how to close up the last bit of opening it always says to "slip stitch" it closed. How exactly do you do that? Please be blatantly obvious in your directions, as I can get confused easily when it comes to sewing! Can you tell that you've finished it by hand when you slip stitch it or is it pretty well hidden? I always look at handmade dolls in the store and can never figure out where they finished off the opening!
