Its simplest form is that of a stencilled border in flat tints used either in place of a cornice or as the border of a wall-paper is used. This, of course, is a purely mechanical performance, and one with which every house-painter is familiar. After this we come to borders of repeating design used as friezes. This can be done with the most delicate and delightful effect, although the finished wall will still be capable of withstanding the most energetic annual scrubbing. Frieze borders of this kind starting with strongly contrasting colour at the top and carried downward through gradually fading tints until they are lost in the general colour of the wall have an openwork grille effect which is very light and graceful. There are infinite possibilities in the use of stencil design without counting the introduction of gold and silver, and bronzes of various iridescent hues which are more suitable for rooms of general use than for bedrooms. Indeed in sleeping-rooms the use of metallic colour is objectionable because it will not stand washing and cleaning without defacement. The ideal bedroom is one that if the furniture were removed a stream of water from a hose might be played upon its walls and ceiling without injury. I always remember with pleasure a pink and silver room belonging to a young girl, where the salmon-pink walls were deepened in colour at the top into almost a tint of vermilion which had in it a trace of green. It was, in fact, an addition of spring green dropped into the vermilion and carelessly stirred, so that it should be mixed but not incorporated. Over this shaded and mixed colour for the space of three feet was stencilled a fountain-like pattern in cream-white, the arches of the pattern rilled in with almost a lace-work of design. The whole upper part had an effect like carved alabaster and was indescribably light and graceful.
The bed and curtain-rods of silver-lacquer, and the abundant silver of the dressing-table gave a frosty contrast which was necessary in a room of so warm a general tone. This is an example of very delicate and truly artistic treatment of stencil-work, and one can easily see how it can be used either in simple or elaborate fashion with great effect.
Irregularly placed floating forms of Persian or Arabic design are often admirably stencilled in colour upon a painted wall; but in this case the colours should be varied and not too strong. A group of forms floating away from a window-frame or cornice can be done in two shades of the wall colour, one of which is positively darker and one lighter than the ground. If to these two shades some delicately contrasting colour is occasionally added the effect is not only pleasing, but belongs to a thoroughly good style.
One seldom tires of a good stencilled wall; probably because it is intrinsic, and not applied in the sense of paper or textiles. It carries an air of permanency which discourages change or experiment, but it requires considerable experience in decoration to execute it worthily; and not only this, there should be a strong feeling for colour and taste and education in the selection of design, for though the form of the stencilled pattern may be graceful, and gracefully combined, it must always—to be permanently satisfactory—have a geometrical basis. It is somewhat difficult to account for the fact that what we call natural forms, of plants and flowers, which are certainly beautiful and graceful in themselves, and grow into shapes which delight us with their freedom and beauty, do not give the best satisfaction as motives for interior decoration. Construction in the architectural sense—the strength and squareness of walls, ceilings, and floors—seem to reject the yielding character of design founded upon natural forms, and demand something which answers more sympathetically to their own qualities. Perhaps it is for this reason that we find the grouping and arrangement of horizontal and perpendicular lines and blocks in the old Greek borders so everlastingly satisfactory.
It is the principle or requirement, of geometric base in interior design which, coupled with our natural delight in yielding or growing forms, has maintained through all the long history of decoration what is called conventionalised flower design. We find this in every form or method of decorative art, from embroidery to sculpture, from the Lotus of Egypt to the Rose of England, and although it results in a sort of crucifixion of the natural beauty of the flower, in the hands of great designers it has become an authoritative style of art.
Of course, there are flower-forms which are naturally geometric, which have conventionalised themselves. Many of the intricate Moorish frets and Indian carvings are literal translations of flower-forms geometrically repeated, and here they lend themselves so perfectly to the decoration of even exterior walls that the fretted arches of some Eastern buildings seem almost to have grown of themselves, with all their elaboration, into the world of nature and art.
The separate flowers of the gracefully tossing lilac plumes, and the five-and six-leaved flowers of the pink, have become in this way a very part of the everlasting walls, as the acanthus leaf has become the marble blossom of thousands of indestructible columns.
These are the classics of design and hold the same relation to ornament printed on paper and silk that we find in the music of the Psalms, as compared with the tinkle of the ballad.
There are other methods of decoration in oils which will meet the wants of the many who like to exercise their own artistic feelings and ability in their houses or rooms. The painting of flower-friezes upon canvas which can afterward be mounted upon the wall is a never-ending source of pleasure; and many of these friezes have a charm and intimacy which no merely professional painter can rival. These are especially suitable for bedrooms, since there they may be as personal as the inmate pleases without undue unveiling of thoughts, fancies, or personal experiences to the public. A favourite flower or a favourite motto or selection may be the motive of a charming decoration, if the artist has sufficient art-knowledge to subordinate it to its architectural juxtaposition. A narrow border of fixed repeating forms like a rug-border will often fulfil the necessity for architectural lines, and confine the flower-border into limits which justify its freedom of composition.
If one wishes to mount a favourite motto or quotation on the walls, where it may give constant suggestion or pleasure—or even be a help to thoughtful and conscientious living—there can be no better fashion than the style of the old illuminated missals. Dining-rooms and chimney-pieces are often very appropriately decorated in this way; the words running on scrolls which are half unrolled and half hidden, and showing a conventionalised background of fruit and flowers.
