This super cute penguin and hamster were made using the Hamanaka needle felt kit. You can buy this from Etsy which I've linked below. Please note that the kit sold on Etsy does NOT come with needles so you have to buy them separately. Be sure to get a felting mat as well if it's your first time doing this. Alternatively, you can use a flat sponge or some melamine foam (Magic Eraser) as a felting mat.
