The other day, on The Camp, I mentioned my use of bulletin boards for miniature storage http://stalbertmini.blogspot.ca/2013/03/not-totally-wasted-weekend.html
One of the campers asked about fastening the hanger to the bulletin board so I thought I would show a picture here:
Centre a heavy-duty clothes hanger across the top of the bulletin board and drill holes through the bulletin board below the far flat sections of the bottom of the hanger. Cut two lengths of wire and put one through each of the holes in the bulletin board. Wrap the ends around the bottom of the clothes hanger and twist the ends together securely.
One of my friends used large ceiling tiles instead of bulletin boards to store many of her lighter items such as printies and small bags of materials/supplies.
