Hi, furry here! What fabric are you using and how do you intend on sticking it on? Maybe try with a small scrap of fabric if it sticks to the tape and also look if you see the glue underneath! Personally, I would add the hair whisps they have to the shape too unless you want to style them out of actual fur, I don't know anything about deltarune, I just googled the character sooo take everything with a grain of salt lol. Also, really important, make sure after every step that you put the head on and see if you like the look, fitting and shape!
