The pattern has instructions for 2 sizes of tree skirt: 48 1/2" octagon (uses Lil' Twister) and a 16 1/2" octagon (uses Ittt Bitty Primitive Pinwheel Tool). There are also instructions for a Table Top Twister that's a 16 1/2" octagon (Itty Bitty Primitive Pinwheel Tool). Let me know if you can't find it.
