They're a little big.

But luckily since the nappy cover pants are made of wool, hopefully now that I've washed them in a hot wash they'll shrink a bit.

What happened was I used knitting needles I already had instead of the right size ones. And now I'm knitting another pair with hopefully the correct size. It's a bit trial-and-error when I knit, since I tend to knit looser than most patterns assume, therefore I need smaller needles to get the same size stitches. And honestly I can't understand HOW anyone can knit tighter than I do and still fit needles into the loops.
