How does one go about installing brackets for shelves?
First, find where you want to put the shelves. Then take a rail
and mark through the holes onto the wall with a pencil. Now, put
the rail away and set an anchor into the marks, and align the rails
with the anchors. Drill a screw through the middle part of the rail
into the adjacent anchor, and make sure the rail is straight. Do
these steps for each anchor, and decide how wide you want your
second rail to be. Install it the same way you did for the first
rail. Now, slide the brackets into the rail where you want them to
be. Make sure the brackets are placed in the same places on the
left and right rail. Now, set your shelves onto the brackets.
