It might be easier if you can get a real live person to show you! Do you know anyone who can crochet? But basically you do a row of chain, then you enter the hook into the stitch next to the hook, put the wool round the needle, pull back through the stitch, you should have two loops on the hook, wool round hook again, and pull through both loops, then repeat in the next stitch so you'll be working from right to left whereas the chain you would be going left to right. This is double crochet, or if you're american, single crochet! Hope that helps but probably you'll need someone to show you!
