for vertical leveling, hang string with washers/a bolt tied to the other end from the top to the bottom of the wall. turn your fan off so they don't sway.

look at the wall and make a mark on your string where you want the top of the top-most frame. take your strings down, lay them out next to each other and make equal marks on all of them. add an inch or two to the height of the frame and measure that out on your string. make more marks on the strings for guidelines. put them back up.

for horizontal leveling, make your own with a perfume sampler tube and some water. measure it into thirds (just the tube part where there's water, not including the cap) against a ruler and use it for leveling your frames after they're on the wall.
