Easy enough to buy, comes in small jars, best if mixed with a small amount of water to make it more pliable/ workable. Washes away easily with water. You can also heat it in the microwave for like 10-20 seconds to make it soft but it will firm back up. 1/2 cup warm water to 1 jar of fluff is a good ratio for mixing. If its too watery just carefully drain off the excess water to the desired consistency. Add food coloring for vibrant colors.
