Recessed outlets! Furniture can be placed against the wall. Who knew?
And for me, one of the most important tools when designing, building, installing or hanging artwork is using a LEVEL. I can't tell you how many times I have had to ask builders to make changes because things were not straight and level. When you are hanging art walls if the frames are not level it is not going to have the same impact.
So how happy am I that I have this handy little tool? Did you know your iPhone could be a level?
It is a free app called iHandy Level. Now I will never leave home without a level!
