Always remember that you need to work within health and safety guidelines when using materials. Scalpels and razor blades should always be used with care, and when they are not in use their blades should not be left exposed.

Note too if any of the fluids you use are flammable or toxic. Bleach, for example, is a very handy and cheap method of removing waterbased ink, but it is very toxic and must always be handled with care.
