I totally get the struggle of finding the right pattern—when I was learning to knit, I found Ravelry super helpful for finding cool designs. For a Howl's Moving Castle cardigan, try searching for patterns that have a lot of garter stitch since that’s easier to manage. It’s all about enjoying the process, so don’t worry too much about it being perfect. I remember making a costume piece for Halloween once, and even though it wasn’t flawless, it was such a hit with my friends.
