This consists of covers with leaves of flannel. Decide upon the size of
leaves, which should not be too large and in good proportion. One piece
of flannel should form two leaves, as in booklets described in Problem
I. Plan the covers to be one-eighth of an inch larger in each direction
than the leaves. These should be constructed like the calendar mount
already described in A, but the space between should be greater,
perhaps three-eighths of an inch. Make dimensioned sketches of all
parts. The parts should then be laid out, cut, and pasted. Finish the
edges of the leaves by pinking (cutting in small points). Four leaves
are sufficient. Sew them to the cover as described in Problem I.
