In using illustrative material it is often advisable to have examples of both the good and the poor. When this is true, one must remember to finish with the good. In other words, start with the poor and contrast with the good; or start with the good, contrast with the poor, and then go back to the good. Illustrative materials can not serve such purposes successfully unless they are so arranged as to be easily accessible for class use. For example, the small fabric sample mounted fast to a sheet of paper can not be examined adequately for texture study. It would be far better to have larger samples which are unmounted, thus making possible not only design, color, and texture study of them, but also many variations in combinations. The bulletin board and screen, well placed, offer good possibilities for accessibility of certain illustrative material which does not need to be handled. The screen is preferable because it can be moved around and placed to the best advantage for vision and light. To the extent that pupils have contact and experience with real articles and materials, there will be a better carry over and thus a greater ability to solve everyday art problems successfully. 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. Good storage for illustrative materials offers many problems, but is that sufficient excuse for a teacher to leave materials on the wall the year around or piled carelessly on open shelves in the classroom? The provision for adequate storage does not necessarily require elaborate equipment nor a large expenditure of money. Cabinets and steel filing cases are highly desirable but are not absolutely essential for good storage. Much of the illustrative material for teaching related art lends itself to storage in manila folders and large envelopes, but some could better be stored in boxes, and still others, such as posters, swatches of fabrics held together by large clips, or pictures, may be best hung up.
