craftgrrl | Question for crocheters

Ok, here's a quick question for all you expert crocheters. I'm teaching myself how to crochet, and I have the actual stitches down, but I'm having a problem at the end of my rows. When I get to the last stitch in the row (the one from the turning chain of the previous row) where exactly am I supposed to make my stitch? I understand that it is supposed to be in the last chain from the turning row, but do I put it in both the top loops, or just in one loop like when you work on the foundation chain? I hope that this is a somewhat clear question, it's hard to describe with out a picture!

Thank you so much!
