I used a bit of wire cable. Bit of black single core from 13amp household cable.
Put a screw with washer into the MDF board (edge) looped the wire round that and tightened the screw.
Top bit I looped it over the existing pegs and wound it around itself and gaffer taped it.
Dont look good but works.
Gotta change it sometime and was thinking of some small chains. Ya can get small stuff from B&Q.
