Secure a small pad. Plan covers, as described in B, which shall project
about one-eighth of an inch in each direction beyond the pad. Plan to
have the space between them about ⅜ of an inch more than the thickness
of the pad. When the covers are finished, paste the pad firmly to the
inside of one cover. If desired, loops of vellum to hold the pencil may
be pasted on the side of the pad, as described in Problem I.
