Not only is it very unhealthy in an enclosed space, but it will migrate throughout the house and it is conductive, so the possibility of destroying TV's and computers and any other electronics is very real. Wet sanding is obviously fine.You dont need much really, just a workbench or two and some wall racks for storing fabric. Couple of drawer units or other storage solutions for things like scissors and knives and you're ready to roll.
