Making Cyanotype Prints by Sue Reno
- Mix the solution according to the package instructions. Paint it onto fabric and let the fabric dry in a dark place.
- Working in dim lighting, pin the treated fabric to foam board or similar portable surface.
- Mask the surface to form a design. Possibilities include leaves and flowers, foam shapes, stencils, stick-on letters, or printed transparency sheets.
- Hold the masking materials in place with small pins, or cover with a sheet of glass or plexiglass.
- Place the board in sunlight. Tilt the board if necessary to match the angle of the sun. A ten-minute exposure is standard–decrease the time slightly for bright mid-day summer sun, or increase it for less than optimal conditions. The fabric will turn grayish as it exposes.
- Make small samples and keep notes before starting a large project. Images that are somewhat over- or underexposed are still very usable.
- Bring the boards back inside and remove the masks and pins. Wearing rubber gloves, rinse the fabric in several changes of warm water, adding hydrogen peroxide in the last rinse (suggested as an optional step, but I recommend it). Watch the magic happen as the print develops!
- Lay the fabric flat and allow it to dry completely.
