Across one wall,
mount a series of ‘hooks’ made from ply and dowel. To do this, cut ply discs using a drill fitted with hole saws of various diameters. Prime and paint one face of each disc. Let dry. Cut a 30–50mm length of thick dowel for each disc. Drill a centred hole through length of dowel (the hole saw will have drilled a hole in each disc). To fit hooks, drive a screw through each disc (painted side out) and dowel into wall studs or masonry wall plugs.
