These labels are made from wooden craft sticks. I painted them a pale aqua to go with other accents already in the room. Then I wrote on them with a Sharpee permanent marker. Finally, I did a quick coat of Satin Polyurethane for durability.
They are applied to the cabinets with 3M poster strips (the kind that can be removed if necessary so no worry about damage to the cabinets). Hint - cut the 3M strips in half long ways and they will go further. I used one strip per label - one half on each end.
