Cyanotype works fine on all organic fabrics, like cotton, linen, silk.The
exposures are very long, compared to paper. Gum arabic can be used with
textile colorants, damp fixed and washed, otherwise it makes the fabric
stiff. Lazy students prefer to use a ready made Liquid Light emulsion from
Rockland or other sources. Sometimes one needs to impregnate the fabric
first. Galina.(galina@telepost.no)
