You can also use needle felt to add designs to things too. It doesn't have to be 3d. And wet felting is good fun too. Another aggression buster!
I have a cute fox to make next, a Jenny Barnett kit, that I'm really looking forward to making. And a friend gave me a little kit from Hobbycraft that has a giraffe & lion in it. That one one feels slightly like it's cheating as they have polystyrene cores.
I've previously made a sheep, from a magazine pattern & a free form duck
The kits are good as they come with the needles, the sponge & the right coloured roving.
