LEATHER WORK

Leather work, like weaving and pottery, is of very ancient origin. The New Testament text concerning "new wine in old bottles" referred to bottles of leather, or wine skins. We read of leather as having been used in still earlier times for shields, saddles, harnesses, parts of chariots, and as an accessory to clothing. In the middle ages the "gentle craft of leather" was not confined to the shoemakers' useful productions but included much ornamental work. There were wall coverings of leather with designs carved, or modelled, or stamped with hot tools; seats were upholstered and books were covered with tooled leather. Some of this work was richly adorned with painted and gilt figures like the celebrated Spanish leather.

Why Leather is Suited to Decoration.—Leather seems, therefore, to have won the right to a high place among the materials suited to decoration. Its beautiful texture, the rich brown tones of its natural colour, the ease with which it takes dyes, and the readiness with which under proper treatment, it receives and retains the marks of the modelling tool, qualify it to minister to the artistic sense no less than its durability enables it to serve the more common uses.

Limited Decoration Desirable.—The tooling of leather is based upon the fact that, when wet, the fibre yields readily to compression and receives impressions that are retained after the leather is dry. But the beauty of design depends upon the colour and texture of the surface quite as much as upon the figured impressions upon it. It is therefore a good point in design not to cover the surface so completely that the peculiar beauty of the material itself be lost. The decorations should be bold and rich, but the tooling should be confined to a small part of the surface. Calf skin and cowhide are well suited to tooling. They are supplied in two general forms, viz., the smooth, generally as Russia calf, and the rough or split cowhides, known as ooze. Leather may be stained a variety of colours by aniline dyes; but since the natural colour of leather is brown, brownish tones are more satisfactory than the blues, greens, violets, grays, etc., because they seem more sincere.

Leather-working tools

Tools.—The simple tools required for tooling leather may be purchased at small cost, or they may be made from cheap nut picks by filing these to shape, polishing them, and buffing them. The illustrations show two different tools, each double pointed. A and B are different views of the first tool; C is the second tool. The narrow pointed end of the first tool is for outlining and working into corners. The broad, flat end is for smoothing down and for general use; the broad tool should be used whenever possible. The round point on the left end of C is used for outlining and transfering the design to leather. The right hand end of C is known as the background tool. It is cupped out like a nail set, as indicated by the lengthwise section just above and by the end view at the extreme right; in fact, a nail set may be used for the same purpose. The background tool, however, is to be used sparingly. If used to excess, especially on large surfaces, the result is likely to have a mechanical and "shoppy" appearance.

PROBLEMS
TO DESIGN AND TOOL A BELT

The sizes given in the illustration on [page 325] are typical, but it is expected that in this and other problems, dimensions will be varied to suit conditions. When the size has been determined the leather should be cut a little longer and wider than the final dimensions are to be, to allow for attaching the belt pin or buckle. The strip of leather should be thoroughly soaked in cold water and then rolled in dry cloth until the leather is dry enough for tooling. It is essential that there should be absolute uniformity of moisture. If on applying the tool, water follows pressure, the leather is still too wet. If it should get too dry to retain the mark of the tool it may be sponged on the back. There is danger of water stains, however, if the entire back is not wet.

Two belt designs

The Design.—The illustration shows two treatments. An interlaced pattern is shown in A which concentrates the interest at the ends and in the middle of the back. The pattern shown is tooled solid and the background is left untooled. If the pattern be tooled in outline it is well to shade these outlines out into the background in order to give relief to the interlaced bands.

Modelled natural forms are shown in B. In this the background is tooled down, but is heaviest at the ends or in the spaces against the raised forms. This gives the background a richer appearance than it has when tooled absolutely flat. Both patterns here shown are straight with parallel sides. Other shapes are possible—for example, those wider in the middle and tapering toward the ends.

When a satisfactory design has been worked out and drawn it is transferred to thin bond paper. The greatest care should be taken not to have any pencil marks on the back of this paper, for they leave a dirty gray stain on the leather which is difficult to remove. It may be added here that whenever it is desired to mark the leather for any purpose a tool should be used, not a pencil.

The Process.—As soon as the leather has dried just enough to retain the marks, the pattern should be placed upon it, pencilled side up, allowance being made for trimming to the desired width. The paper may be held in position by thumb tacks, which must not, however, pass through the leather inside the part that is to be cut off. The pattern may now be traced through the paper, over the lines of the drawing, with the round pointed tool. Care will have to be exercised to make sure that the pattern is completely transferred to the leather. When this is accomplished the pattern should be removed and the lines, which will be found somewhat dimly traced on the leather, should be immediately deepened by going over them with the same tool.

Method of using the broad tool

The next step is to tool down the design; and in doing this the work should be turned under the tool rather than the tool itself on the work, in order that the pressure of the tool may be applied at the edge of the pattern farthest from the hand. This not only insures a correct and convenient position of the tool, but allows a perfect view of the work. In this part of the process the broad tool should be used, moved sidewise, as shown by the direction of the arrow in the accompanying cut. In working up into corners the narrow tool may be used if necessary. The movement may be described as "ironing the leather down." The surface should not be roughed up or cut up into "shoulders." It is a process requiring time. One should not try to get the full depth with the first pressure of the tool. One should coax the surface and add pressure with each succeeding stroke, taking care that the tool does not scrape. It should glide; and yet, on the other hand, beginners will perhaps need to be cautioned not to wear out the surface by feeble scratching and patting. A firm, even gliding pressure does the work. As the leather dries it will be seen that the tooling has given it a dark, glossy surface. When the process is completed the belt may be trimmed down with a firm, sure cut of the knife, using a straight edge wherever straight lines are desired.
