Labels should be as small as possible and still be readable. Print the labels on card stock. Dr. Richard Brown strongly suggests that the labels be oriented along the length of the body. In any case don't let the labels detract from the specimen. Work on overall appearance and neatness.
Collections often look unkempt.
Attention to insects' height on pins helps prevent this. Also, arrangement in the box is important. No collection should go to State Fair with less than 50 insects and none should go to the Mid-South Fair with less than 100. Arrange them alphabetically by Order and place them neatly evenly spaced in the box. Yes if you add 25 new insects next year you may have to rearrange the entire box, but we learn in this manner.
