Bookbinding for Beginners - 8

by Florence O. Bean - Assistant in Manual Arts - Boston Public Schools

Mount a Calendar or Picture

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 news board, covered back and front with a bookbinding cloth.

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, illustrated by Plate IX. 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.

Working drawings should now be made of the completed model, showing the location of the calendar, also of the front and back. Make them either accurately or freehand as described in Problem IX. If the latter method is used, some sense of proportion should be observed. That is, do not draw 3 inches as long as 6 inches, nor 4 inches longer than 7 inches.

The size of the foundation has already been determined. The front covering should be 1/2 inch larger on each side than the foundation, to allow for laps which are to fold onto the back of the news board. The back covering should be from 1/16 to 1/8 of an inch smaller than the foundation on each side, as the finished product looks much neater if no raw edge is visible from the front.

In Plate X, the first drawing is of the face of the completed model showing the location of the calendar. This also shows the size of the foundation. The other two drawings show the size of the two pieces of vellum. If the first drawing seems too complicated, omit the location of the calendar, and draw and dimension only the outside rectangle to give the size of the foundation.
