What is the minium amount of supplies I would need to paint a room?
You need a 1 1/2″ cutting/trim brush, for the top edge of wall and the corners. You will need one 3/8″ roller. You can actually buy the little kits that come with pan, rollers/roller handle, and brushes. That would be the most simple, that and your paint. Also, be sure to get a cheap plastic dropcloth to put on the floor and some blue painter’s tape to tape trim edges and baseboards and whatever else you don’t want paint on. I would say you are looking at maybe $20-30 total. You should only need a quart of paint, two max.
