A marble pattern consisting of but one or two
colors, and usually used on the edges of books.
The colors are diluted to about one-third of their
normal volume with water, and, when two colors are
employed, enough gall is added to the first color
to make it spread on the size to form a ribbon 5
to 6 inches wide, while the second color is
applied evenly in fine drops, followed by a
sprinkle of water which forms the hair veins.
Carragheen moss is the usual sizing for this
marble. Single-color hair marbles include the
black, red or blue, while two-color hairs are
usually red and black or bluish-brown. (151 )
