There was a huge towel bar in our first floor powder room.
It really wasn't necessary since all that needed was a hand towel.
My mom gifted me with many do it yourself tricks - One of which is spackling a hole.
Here is a quick run through...
Purchase your spackle... Only a few bucks and can be found at even Walmart or Target.
Take a damp papertowel and do a quick, low pressure wipe across to clean off the excess.
We just painted right over it with our new wall color and you don't even notice it!
Go forth and fill all those holes that you strategically covered with frames!
(Now, I need to go to town with that spackle in my girls room. Hung some branches and left about 20 holes! :)
