The only lesson from this "fail" is to always measure. Remember when Laura, Landon and I took a trip to IKEA? Well, one of my purchases for the day were three Lack wall shelves.
I intended to put them in the guest bathroom above the toilet, but when I went to hang them up, it was evident that would not work.
They are about a foot deep, so putting them above the toilet required hanging them super high in order not to have tall guests (or Landon) hit their heads on them. So, we are now in the process of determining where the Lack shelves will fit best. We may put them in the closet "office."
