This is my first ever made furtail (made in a couple of hours today because I had to handsew it. My machine didn't like the thick fabric) which is super light and super soft/petable. I came up with a system that requires no foam and keeps the shape of the tail while someone wears it (It also moves and comes to life like a tail should ^^).
