A good idea is to place a bucket of water in the room then take a 1.5m 2x4 plank and wrap it (the full length of the plank) in a natural fiber rope made of cycle say about 15mm thick. (should almost look like a cats scratching pad) Place the rope covered wood into the bucket of water.
The rope will draw the water up and evaporate adding humidity to the room.
