The border-line between educational handwork and technical bookbinding
has now been reached, and it is not the writer’s purpose to cross
it. If this book of problems assists others in solving the quest for
interesting and educational handwork, its mission will have been
accomplished.
Transcriber’s Notes:
Italics are shown thus: _sloping_.
Small capitals have been capitalised.
Variations in spelling and hyphenation are retained.
