Mark a plumb line
Wipe the wall, let it dry and draw one straight vertical guide so the first panel starts true.

UP CLOSE
Calder pairs narrow upright strips with a dark felt backing. Stand back and the felt becomes a run of thin shadow lines; flip the panel over and that same felt is what takes the glue or tape.
Strips on a felt backing · nine tones · glue or tape onto a smooth interior surface · narrow it by slicing the felt with a utility knife, shorten it with a fine saw · not for bathrooms, basements or outdoors · a microfiber duster keeps the strips clean.
INSTALL IN THREE MOVES

02Slice the felt between two strips to make a panel narrower, or use a fine saw to shorten it.
03Add glue or tape to the felt, line the edge up with your guide and slide each new panel snug against the last.
