OOoooo I have a question for you about this (well, similar) So, in order to make something round, you don't have to make it bigger and warped for it to turn out right?? I've been trying to figure out how to make Zero in plush form (you know, from Nightmare Before Christmas? ) but I could not figure out how to do his head! Halp? You seem good at it
For a round-ish head, you probably do have to exaggerate the curved shape so that it will stay a nice pronounced round shape after you have stitched the two head pieces together and turned the whole thing inside out. Maybe draw the curved part (and only the curved part) a 1/2 inch- 1 inch wider? This will give you more room for stuffing, which is where most of the "roundness" will come from. Just make sure to put more stuffing to the sides.
It's a little hard for me to explain in words, sorry! Hope I was of help to you. Show me when your plush is done.
I am totally going to pick your brain while trying to quasi-teach myself how to make plushies. I think felt things are adorable, I just need to attain the skills. And I shall definitely share the plushiness when it is completed. Might have to wait til summer though when I only have to worry about 2 jobs and not school too
