 gingham, printed in red and black. 



These printed fabrics may be made up into 

 bags, as shown in Fig. 17. A twisted cord with 

 several bright beads strung upon it gives a 



In planning surface rhythms we again make 

 use of a device that removes much of the 

 difficulty of drawing and that saves much 

 time. Squared black paper can be bought, or 

 you can rule black construction paper into

finishing touch. Such a bag may hold a dus- 

 ter, or it may be used for a work bag. 



Problem 3; Transforming a Biscuit Box. 

 When you print a number of stripes, side by 

 side, on ruled paper or on cotton cloth, you 

 establish another kind of movement which 

 carries the interest in another direction. Not 

 only does the eye move in the direction of a 

 border, but it travels over a surface, if it is 

 attracted by interesting shapes and colors. 

 Designs that are carried over a surface and 

 that establish movement in two directions are 

 called surface rhythms. They are used in 

 wallpapers, textiles, carpets and rugs, for inlaid 



squares yourself, using a ruling-pen and the 

 white, opaque water color known as "letterine," 

 or white show-card color. The squares should 

 measure about a quarter-inch on a side. With 

 the black squared paper as a background, with 

 white letterine and a No. 6 water-color brush, 

 you can make many interesting surface 

 rhythms. Fig. 18 shows a beginning; here a 

 group of four squares has been filled in with 

 white, and this unit has been repeated at 

 regular intervals over the sheet. You can see 

 that this makes a monotonous design. Our 

 problem is to make it interesting. The back- 

 ground shapes need to be modified. In Fig. 19

floors and mosaics and for any other purpose 

 where a decorated surface is desired. In all 

 such designs there should be the same rela- 

 tionships between repeated unit and back- 

 ground that we found necessary with border 

 rhythms. 



this has been accomplished by the addition of 

 three horizontal bands in alternate squares. 

 The design now has quality, and is worthy to 

 be put to some practical use. 



Bright color effects may be used with sur- 

 face rhythms if we are careful to select color
