All kits include 2 new felting needles and include everything you need. You will need a foam pad or sponge to use as a work surface. We have two sizes of foam pads available in our shop that will last through many, many projects. Since each kit includes 2 sharp, barbed, felting needles we recommend them for ages 10 and up. Younger children have been very successful with needle felting but of course adult supervision is highly recommended for anyone under the age of 13.
