These pretreated cotton cyanotype squares from Blueprints allow one to make photographic quality images in white on a blue background, with the utmost ease. The cotton squares have been treated with Potassium Ferricyanide and a ferric salt. When exposed to sunlight the fabric will turn a bright blue color, like a blueprint, except wherever it was covered. So if you put a leaf on top of the square, expose it to light, you will have an image of near photographic detail of the leaf against a blue background.

Blueprints Cyanotype pretreated squares are the easiest sun printing product out there. Just pull out a sheet from the package, cover it with your object/design/etc. expose to sunlight, rinse and dry and you have a nice detailed print.

You can also create photo negatives by printing or drawing images on clear transparency sheets. Just lay the transparency sheet on the piece of fabric and then place a piece of non uv blocking glass or acrylic on top of the transparency to hold the transparency in tight contact with the treated fabric or paper.

Mixed Pack contains four of each color.



Blueprints on Fabric Instructions

Please read all instructions before opening bag
  • Do not expose fabric to direct sunlight until ready to print!
  • Do not get fabric wet before or during exposure. Make sure your hands are dry before handling the fabric. Also be sure that what you place on the fabric (and what you place the fabric on) to expose is dry.
  • Always use gloves when handling fabric.
  • Practice on a small sample piece of fabric first to get used to the process. Fabric will be yellow-green when unexposed. The final blue color will not be visible until the fabric has been printed, rinsed and dried. Design blueprints using almost anything, leaves, lace, toys, confetti, drawings on acetate transparencies, old glass negatives....
  • Unexposed fabric CAN be ironed before exposure. Use a DRY iron that does not spit or leak water. Use a cotton or silk setting (depending on fabric to be ironed). Iron on wrong side of fabric and/or use a pressing cloth.
  • A small amount of 3% Hydrogen Peroxide (1 teaspoon H.P. to one gallon water) can be used in the first rinse water. This will cause the blue color to immediately deepen to it's final color.
  • Use within 6 months for best printing results (bright blues and good contrast).
  • Store extra fabric in black plastic bag in a cool, dry place.

PLEASE NOTE: The fabric or paper will tend to darken over time even when sealed in black bag - do not assume that fabric or paper is expired - give it a try - sometimes all that is needed is a longer rinse in hot water after exposure.

Important Care Instructions

  • Blueprints are photographs – not dyes.
  • The image is permanent, but the blue color will change to yellow if washed with phosphates, soda, borax or bleach.
  • To preserve the original blue color – hand wash using only a small amount of NON-PHOSPHATE liquid soap. Rinse thoroughly and dry flat.
  • Dry cleaning is NOT recommended.
  • Blueprints can be ironed using a dry iron. The blue will change slightly while warm and return to the original color when cool.

Blueprinting Instructions

1. Prepare design indoors out of direct sunlight.

2. Pin fabric to cardboard or foam pinning board.

3. Arrange design objects on fabric.

4. Pin design objects in place or cover with a piece of safety glass (non UV blocking).

5. Take prepared fabric outside and place directly facing the sun.

6. Exposure time is approximately

  • 5-10 minutes on a warm, sunny day
  • 15-30 minutes on cooler days

7. Remove from direct sunlight and then remove design objects.

8. Rinse fabric thoroughly in plain water until water runs clear.

9. (Optional) Add a teaspoon of hydrogen peroxide to the rinse water . This will cause the blue color to immediately deepen to its final color - otherwise the blue color will deepen over a period of 24 hours.

10. Lay flat, OUT of direct sunlight, until dry.


Trouble Shooting

  • Blurry prints: This is a contact printing process. Transparencies and negatives must be firmly in contact with the fabric. Pin carefully, or use a piece of heavy glass to press design elements to fabric. Board must be perpendicular to the sun for even exposure. Printing in cloudy weather does not provide distinct shadows
  • Water spots: Caused by wet hands or wet leaves dripping on the fabric or paper before or during the process.
  • Streaks: Brown on back of print, dark line on front. Fabric or paper not well rinsed. Rinse again immediately.
  • Dark blue prints: Black areas of transparencies not dense enough, too little toner or ink. Too long in the sun, reduce exposure time. Not well rinsed, and print continues to expose.
  • Very pale blue: Hazy, cloudy weather, very cold, pale winter sun, too little exposure.
  • Surprise prints: Remove ravels, pins and extra items from board before printing.
  • No print: The glass or plastic cover piece has UV blocking.

These are very fun and easy. I got really neat results using a dried out sea fan I got at a nature store. Doilies and old lace are great too. Highly recommend getting the plastic glass to hold things down in close contact with the fabric.

This is an excellent product for kids and adults! For kids it's an excellent summer sunny day project. It's a bit like magic watching the shapes appear. We used it for my daughter's birthday party...very fun...not messy and every child takes home an interesting experience and a beautiful image. It was a big hit.
