Tunisian Crocheting!

So, in 2009 I got a few things for x-mas

1. yarn (blue-ish-green)
2. yarn  (yellow/orange/red/pink)
3. Tunisian Crochet hook
4. card with info about a web site that would teach me how to Tunisian crochet

                                        After about a moth I thoroughly  forgot about these items. Then I found the hook and decided why not learn? I went to the website and found no useful info, so I googled it. I found a tutorial video and started trying! So far I'm failing miserably... does anyone have any tips for me?
