safety goggles or pine cones?
a fabric store wil have many options, something low sheen is best i have found, try a fabric store, see how the fabrics respond to the light when you move it about, anythng to reflective or shinny will make problems, i forget what the nouns of the fabrics are, i use black fabric for black and for white use a white wall, for colour i gel a flash and fire it at a white wall,
Both offer contacts for doors and windows, glass break sensors, motion detection, video surveillance and/or recording, monitoring services, battery backup, sirens/alarms, etc. The wireless systems are easier to install and will usually cost less, yet their performance is not lacking. I would recommend wireless from a quality reputable company.
