The parts A overlap and are either pasted together or wired with the machine.

Similar cases of thinner boards—but covered—are made for hymn and prayer books. They are always pasted, covered with a dark pressed paper; and the edge at the centre is cut with a gouge as seen in the adjoining illustration (Fig. 110).
Hymn and prayer books may at times have a cover; this would be cut from stout paper, generally calf-leather paper, the colour of the case covering (See Fig. 111).
Covers made in case form entail more work (Fig. 112). The centre piece has a joint at each side; this part is, therefore, covered with cloth, which extends over the parts B and C, all the rest being covered with dark pressed paper.
