Step 1. To mount blinds
outside the window frame, measure the width from the outside edges of
the window frame and the height from 2 to 3” above to 2” to 3” below the
frame. If the window doesn’t have a frame, measure the opening and add a
few inches on each side. Make a diagram of the measurements and refer to
it when purchasing blinds to fit.
Step 2. Position the first
bracket as indicated by the diagram you made in step 1, and mark its
screw holes. Use a stud finder to locate nearby studs. If a stud is in
the bracket area, drill pilot holes at the marks and attach the bracket
to the wall. If no stud is available, use an awl to make a small hole at
each mark, and then drive a self-tapping hollow wall anchor into each.
Finally, drive a screw into each anchor.
