Hooked on Anime

Hi.

I just found this patterne yesterday, and I am so happy, I can't get my arms down ;)
However. I started working on it, and I find it actually fairly easy to make, except, when I'm done doing one part, and i wanna stuff it, it's like the wholes between stitches are too big. I murdered a cheep pillow from IKEA to use for stuffing, and the wholes between every stich is big eneough so I could easily pick the stuffing. That's not really cool hehe...
So, I was wondering if maybe I'm using a mutch differen yarn and hooksize than you do?

I do'nt know the right terms of sizes where you are from, but here in DK my cotton yarn is labelled 8/4 and the hook size recommenden for that is 2,50 - 3,00. Im using a 2,50 hook, so it should be fairly tight. Or at least I thaught so.
Is it the wrong size or something? I am fairly new at crochetting, but I learn very easily on these things, so after consulting you tube videoes, I'm pretty sure I did all the stitches right. And that is why I think maybe my hook or yarn size is different from yours.

Would it be possible for you to help me out, just by telling what kind of sizes you are using?

I'm sorry, if I made alot of spelling mistakes, It's been a while since I left school, so I do'nt practice my english mutch anymore.....

If you do see this, and decide to answer me, would you then mind doing so on my e-mail? Mariamiss6 @ hotmail. com (do'nt forget to take out the spaces ;) )
