Plate XXIII. A folding picture frame.
If a double frame is desired (see Plate XXIII) make a frame for each picture but use for the back of each a piece of heavy paper which should not have an additional covering. Make a foundation which folds through the center planning to have it extend slightly beyond the frames as shown in Plate XXII; to each half of this foundation attach the frames already made.
C. Either style of frame may be made with a covering of silk, grass cloth, leather, and slightly padded. For this purpose use sheet wadding which should be firmly attached to the front of the foundation. Over this lay the covering material and paste the laps only, not the broad faces.
Problem VIII
HINGED COVERS
Time: 8 hours.
Materials: Newsboard, vellum, paper for leaves, eyelets, cord, and (if desired) cover paper for C and D.
Note: In selecting materials, choose those which harmonize with each other, i.e., the vellum, cover paper, and lining paper should be of the same hue.
The problem is to make two separate hinged covers between which loose leaves may be bound, the whole to be fastened together with macrame or other cord. This may be designed for one of many uses, suggestions for several of which follow (see Plate XXIV).
