I use aluminum flashing for a windscreen. I made an aluminum base for the alcohol stove by cutting a circular piece of flashing that is a little larger in diameter than the base of my pot. I bent the edge of the flashing around the base of the pot to form it. I fill the stove to the desired level and include some alcohol on the base. Lighting the alcohol on the base preheats the stove. I've used this setup in winter (temps in the 20's) on day hikes. When finished, the windscreen wraps around my pot, and the base fits under my pot in the bottom of my pot cozy. So far I have only used this setup for freezer bag cooking, and it works well for that purpose.
