Paper Each child may have his own paper Sack sack with his name label on it. He may keep scraps of all kinds needed for certain craft problems. Tin Cans Coffee cans and other tin cans with lids work well for clay. Each child may have his own can with his name on it. He can put his own clay work in this and it will keep moist. Reversed, the can may be used as working platform which may be turned to view work from any angle. Garbage Cans and Crocks Portfolios Every classroom should have clay to use. A garbage can or crock will keep the clay moist. Any other non-rustable containers may be used. Portfolios for the work of each child or one large one for the group may be used for keeping flat work. Chip board or corrugated board (24 x 36 inches) may be used for large portfolios. Place for large portfolios. Place boards about an inch apart and use 3 inch brown sealing tape as hinge. Twine may be used under horizontal strips of tape placed inside the port- folio for reinforcement. Water If a sink is unavailable, water in pails or large tin cans may be used, one for clean water and one for dirty water.
