Working with items such as scissors and staplers can be dangerous, so be very careful when you use them. Make sure that you never leave them open or lying around where smaller children can reach them. Be particularly careful when you are using the stapler.

Before starting to make any of the masks, cover the work surface you're going to use with some newspaper or an old cloth and make sure that you are wearing an apron or some old clothes. Glue can get everywhere!

When you've made your mask, remember that masks can make it difficult to see, so be especially careful when you're wearing it, especially near stairs. Running while wearing a mask isn't a good idea either!
