CARE AND STORAGE
In addition to collecting and using illustrative materials, the teacher has the further problem of caring for and storing them. Soiled, creased, or worn materials are not only lacking in inspiration but set up poor standards.
Illustrative materials may be most efficiently cared for by—
1. Mounting that from which margins will not detract, that in which only one side needs to be used, and that of which texture study is not important.
2. Avoiding too long or unnecessary exposure.
3. Careful handling.
4. Cleaning if possible.
5. Pressing.
6. Labeling and classifying.
7. Careful storing.
