_Beating Up the Woof._--The weaver presses the right-hand pedal, and every alternate thread separates from the other, leaving a space between the two sets of warp threads for the shuttle to be thrown from right to left, carrying the woof threads through. The operator then draws this thread up at the side to make a good selvedge and brings home the beater, thus pressing the woof into the warp. A sheer fabric requires a light stroke of the beater, while firm cloth requires more force. Releasing the right pedal, the operator presses the left, which causes the warp threads to cross, holding more firmly the woof threads just thrown. The shuttle now passes from left to right, carrying through another woof thread which, in turn, is beaten up as before. So the work goes merrily on with the throws of the shuttle alternating from right to left and from left to right, interspersed with the strokes of the beater.

_The Design._--This problem, like all others in house decoration, involves in its initial stages questions of design. Before planning the rug it is necessary to know what use the rug is to have--whether it is to be for a hall, a living room, a dining-room, or a chamber, and whether it is to be used upon hard wood floors or with a carpet. This is a question of colours, and of materials; for the designer must avoid too sharp contrasts in colour, not only in the rug itself but in its relation to the other colours with which it should harmonize, and the materials used must not display glaring inconsistencies of texture. Unless the beginner has special talent as a colourist it is not wise to attempt the introduction of too many colours in one piece of work. If the warp is dark it is usually better to use light or medium woof. If several shades are used in the body of the rug, better results are obtained by using for the border or end decoration one or more plain colours which match or readily blend with the principal colours of the body of the rug.
_Materials: Denim._--There are many materials suitable for rug making. Denim in moss or forest green makes a rug fit for a queen. This should be woven on a blue or green warp thread of carpet size. In preparing the woof it will be necessary to cut the denim on a true bias into strips from 1/2 to 3/4 of an inch wide. The latter width is better. In cutting, the best method is to fold back one corner of a square cut end along the selvedge, forming a fold across the cloth at an angle of 45 degrees. Crease this fold carefully and make the first cut along the fold. With a yardstick or a straight edge of some kind rule off lightly with a piece of chalk or soft pencil strips of the proper width for the succeeding cuts, taking great pains to maintain a true bias. When a sufficient amount has been cut, the pieces should be ravelled or fringed on each edge by drawing them quickly through a button hook. There is a certain knack in this, but it is soon acquired. The fringed strips should then be fastened together at the ends by means of overhand stitching, trimming off neatly all projecting corners. The moss-like effect when woven is improved if the woof, as soon as it is prepared, is not rolled into balls but left in suitable lengths for filling the shuttle. A special form of shuttle without a bobbin or spool is used for carrying the woof cloth for rug weaving. Its simple construction is shown in the illustration. The woof is wound endwise and unwound in weaving by turning the shuttle.
