They gain more stiches *hope i said that right* and they sometimes loose stiches... oh and be sure your yarn is strong casue it can break. Whats fun and you should try is using fun fur *the fury yarn* and just do a plain knit uhhh I want to say around 20 stiches per row is good... XP but what would I know all I can do is knit and perl... i just learned yesterday how to cast off haha. XD
Fun fur yarn, whilst it can be a wee bit awkward and fiddly is fantastic for someone who's learning! I used it to knit a really long scarf in garter stich when I first started out and the fluffiness hides all manner of sins, so you get good practice at the basic stitch and you still have something wearable at the end!
