If a glass medicine bottle is to be carried constantly in the pocket, it is best to cover it with leather or rubber.
Ill: Pattern for Making a Bottle Cover of Leather or Rubber for Bottles Carried in the Pocket
The sketch shows how to cut the pattern so that it will fit a square bottle. The bottle is placed on the leather, or a piece of paper as a pattern, and the outlines marked upon it. The leather or paper is then folded over four times and cut out as shown. This cover will prevent the glass from being scattered in the pocket should the bottle be accidentally broken. It always provides a means of distinguishing it from other bottles of the same type and size. - Contributed by James M. Kane, Doylestown, Pa.
