drill two holes near the edge of the shelf and use some thick string/thin rope,thats what i done. I used some rope i got from those drawstring bags u get free when u buy stuff from shops such as jd sports, first sport,etc. Works fine,just tie a know that is solid and wont undo! :shock: As for the pins,tie a knot with a loop,where u can adjust it,just like u did when u was a kid and played with ur yoyo ,so that u can take ur shelf out! :lol: Sorted!
