Last, it's perfectly okay for your friends and family to sign your cast. Permanent markers usually work best. Washable ones can smear. It's also fine to draw pictures on it. You can even decorate it with stickers. Be creative! This might make having a cast a little bit more fun.

Doctors use a special saw to remove a cast. It has a dull, round blade that vibrates up and down. The vibration is strong enough to break apart the fiberglass or plaster. It can't hurt your skin. The vibration may actually tickle you! But a word of warning. The saw can be very loud, almost like a vacuum cleaner. Just remember that it will sound much worse than it will feel.

You may want to keep your cast. Perhaps all your friends signed it. If so, just ask your doctor. Many doctors are happy to let people keep their casts.
