PAPER RINGS MADE BY FEEE CUTTING Make curtains or Christmas tree ornaments of paper ringscut in a definite way. Take an 8-inch square for it into 2 equal parts free-hand. Divide each one of theseinto 4 equal parts. Now you have 8 1-inch strips 8 inclieslong to be divided in one of several ^ays according to the sizeof rings desired. One way—Bisect them vertically and horizontally. Another way—^Trisect them vertically and horizontally. Another way—Quadrisect them vertically and horizon-tally. Another way—Trisect them vertically and quadrisecthorizontally. Another way—Bisect them vertically and trisect horizon-tally. MEASURING AND WEAVING LESSON I Bank Decoration (For bank in Ruler Lesson IX, page 93) Material: A 4-ineh square and an oblong 4x3 ofcontrasting color. Eulers: 1234. Compare oblong to square, giving problems. (Relation1 to 2.) ? Compare rulers and estimate length and width of paperswith them. Divide the 4-inch square into 16 one-inch squares,
