Decorating new bedroom for my son who loves posters. At the moment i just use the old fashioned blu tac which i think you can also get in white now.
Does anyone use anything else. I find the heavier posters tend to end up dropping down by a few centimeters every few weeks and eventually fall down. We end up using more blu tac and eventually the room starts to look really untidy with bits of blu tac showing.
Any new inventions i havent heard of?
Thanks in advance.
