I tried a wall but it would not stick. I am 'assuming' that it should cling on either side as I've used both. How can I make this stay up and still be removable?
Make sure the area you are putting it on it absolutely clean. It sticks best if the painted side is facing out. For the hard to stick ones, I've actually soaked mine in warm water for a few minutes, put them on the window and then just blotted away the excess water.
