New paper bags make good holders although less desirable than either of the other two.
Problem III
MOUNTS AND PADS
Time: 6 hours.
Materials: Newsboard, vellum, and paper for memorandum pad, or calendar,
or pad to be mounted.
We shall now begin to deal with materials that are more exclusively employed in bookbinding work. The simple articles considered at first are not books; but because the processes involved and the materials used will be used later in the more difficult work of binding a real book, they are made a part of this course.
The wise teacher will become somewhat familiar with handling the required materials before attempting to give instruction. It is recommended that two or more models from each problem be made by the teacher before selecting one for the class.
The articles described in Problem III (See Plate VII) consist of a foundation of a single piece of newsboard, covered back and front with a bookbinding cloth.
A. Mount of a Calendar or Picture
First secure the article to be mounted and then determine the size and shape most desirable for the mount. Never make the mount first and then attempt to find something to fit it.
To determine the size of the mount, place the calendar or picture on a sheet of paper and find the most pleasing margins by laying a pencil on each side of the article. Increase or decrease this margin by moving the pencils back and forth until a satisfactory position is found, as shown in Plate VIII. Indicate this position by a line on each side. In the same manner, establish top and bottom margins. The margin at the top may equal that at the side, or be a trifle wider or narrower;[1] the one at the bottom may equal the side margins or be wider, but never narrower, and always greater than the top margin. Draw lines for top and bottom and the size of the foundation is indicated. A fraction of an inch may be added or subtracted to give even measurements.
