When I get confused, I have some basic books that have really good drawings in them. I keep the books open to the page I need while I am crocheting and then use the diagrams to match up the loops that I am looking for when I get stuck. The cool thing about crochet is that you can rip out a row and the rest of the work is still intact (unlike knitting, which needs to stay on needles and can unravel easily). The books that I keep on hand are: "I Taught Myself Crochet", "The Harmony Guides: 300 Crochet Stitches", and "The Harmony Guides: 220 More Crochet Stitches". Please note that the Harmony Guides are from the UK, so the name for stitches like single crochet, double crochet, etc slightly different things, but they make note of that in the beginning of the book.
For an online reference to look up a stitch and how to do it with little Quicktime movies (just like Knitting Help's online movies), take a look at the following website. www.anniesattic.com/crochet/content.html?type_id=S
Or if the link doesn't work, go to anniesattic.com and then click on the menu at the left-hand side of the page under Community called "Stitching Help". There is a list of different crochet stitches you can click on for diagrams and Quicktime movie demonstrations.
Hope this was helpful! Keep up the good work!
