Love this SallyFashion memo board set. Included in the pack are 6 hexagon pieces measuring 17.5cm x 15.5cm and they measure 1.5cm in thickness. The idea is that you can assemble the boards on your wall in whatever shape you desire. You can bunch them up together, space them out and even use them seperately - a great idea and making them multi purpose. There are 3 black felt covered hexagons and 3 grey covered, so they suit pretty much anywhere.
There's no need to drill and make unsightly holes in the wall with this set either. Each piece has 4 squares of double sided tape, so you just apply them to a clean dry wall. The board is made of foam, so they are light enough to hold. I personally haven't had the need to move them yet, but the product description does say that it's possible. To get you started on your wall, there are 12 red push pins included. Perfect for the job.
It's a simple idea and done very nicely. Good quality and affordable. Great.
