Due to space constraint this year as we build in a TV console that maximum all white space, so i put my Christmas tree on the wall..
Initially I started 3M stick on hock.. But after first 2.7m went up, which I need about 6, I find it too costly. $6 for two, 6x3 already costed me $18. So I went to local hardware store got got those cheaper version 2 for $1.20 and in order to protect my wall, I replaced the stick with 3M. And that's half of the price. Not very pretty as the 3M isn't the right size, but it's ok, cos it will be all covered up.
