That is an important question :)
Nothing hard, you just need a support to make it real or draw a first concept :)
This whiteboard is composed of 4 stickable panels of 750 mm x 750 mm for a diagonal over 2 meters.
It is easy to apply, and I add 3 extra pen with magnet to put them directly over the wall.
To have metal surface on the wall I just sticked 3 coins of 1cents €.
That's all :)
Step 1: Your Own White Board!
Enjoy and invent on it!
You can create whatever you want :)
And now even your children could draw on your wall ;)
