a little confused.

Hello all, I have a quick and probably dumb question to ask:

I finally found a good tutorial to use for a simple tote bag on ohmystars.net. So last night I decided to finally try it out, or at least do a practice run on some extra fabric I had laying around. Everything seemed simple enough when I was reading it, but when I started to actually do it, I got stuck on the second step. It said to cut out a 1 inch square on the bottom of the 4 pieces of fabric which I did, but, here's my question, how do I sew it? I know that if I sew it normally it'll have a big notch at the bottom. Do I sew everything normally, and then "sew flat"? So now I'm hoping  you guys can point me in the right direction.
