When you are short on workspace and must work in environments that are sensitive to dust or paint particles you have other options besides covering everything with tarps.
Check out the Zipwall which is a temporary barrier that can be fastened in a variety of ways and will keep all dust particles within the enclosed space. The enclosure is sealed with zippers which provide much more protection than clips and tape. Having a barrier makes job cleanup much easier as it keeps all dirt in a confined space. They can be easily installed by one person and the zipwall poles have other handy uses.
