This is a set of letters designed for the top of a school library to label the shelves. There are 3 sets - 2 alphabet (yellow chevron and green chevron) and 1 numeric by 100's (orange chevron). I label the top of my library shelves with large signs and these smaller signs, color coding throughout. Of course, these labels could be used for other classroom decorating purposes. They print out 4' x 6", perfect for framing. I frame in 5"x7" frames, mounting with black paper.
