After a session in the craft roof with a couple of good mates and much discussion this was the end result.
There are 4 velcro dots on the back of the 12 x 12 thick cork tile so that I can take the entire cork board of the wall and put on my desk and then just stick it back when I am finished. The strips are self adhesive magnet which I cut to the size I wanted. Took less than 5 minutes to make and fits perfectly in the gap between the curtain and the book case. What do you think??
