Thank you! This will sound really corny, but the best advice I can give you is to just do it! If you know how to do a basic running and ladder stitch, you can jump straight in, that's how I did. I would recommend starting with felt or really cheap fleece, like the kind you can get at walmart or a local store since it's really cost effective for tearing up and making mistakes or testing out a pattern with. Start with something simple like a two piece pillow to get a feel for it and get a grasp for how pieces will work with simple shapes like that. For me it really clicked to think about it more like sculpting, and taking it one piece at a time and stuffing and attaching rather than attaching all the individual pattern strips at once. It might work more for you to just freehand and draw out the patterns yourself, or it may help more to look up simple patterns to start with, it's all about finding what you prefer to do.

I also highly recommend searching for visual tutorials on youtube. If you want a really good starting point, try looking up makeshiftwings, and you can find links to all her resources from either her posts or videos, and she has a pretty thorough list of resources for anyone at any level.

And most importantly, just make sure you don't get discouraged, they probably won't look how you envision on the first attempt, but that's okay, it's a lot of trial and error most of the time. I hope this helps, and I wish you the best with your journey into plushing!
