Dyeing Fabrics With Tea and/or Coffee 
Also called Tea Staining or "Antiquing" Fabric

There are many varied ways to achieve "antiquing" for fabric, and unfortunately no one way will work for all occasions.  First, there are many different types of fabric; cotton will not dye the same as silk, and polyester will hardly dye at all.  Next is the question of which dying agent to use:  tea, coffee, acrylic ink, or acrylic paint.  I'm sure there are more, about anything that can be thinned with water will work!  The last question to ask is what type of effect are you looking for:  lightly dyed, heavily dyed, dark brown or light cinnamon or a combination of both.  Of course when you factor in the inks and paints, any color is obtainable.   You may dye your project at almost any phase of the construction.  The cloth can be dyed before any layout or cutting.  It can be dyed after cutting, or after assembly and sometimes even after the project is finished.

Once you have decided on the look you want, here is where to start:  Write all of the ingredients and amounts down as you go.  Mix a test dye bath by starting with a heavy concentration of the dying agent, tea, coffee or ink, and just enough water to cover your fabric.  Take a sample of the fabric and test the dye, making sure you note the length of time the fabric is in the bath.  Once the sample is dry, see if the effect is what you are looking for.  If the test is too dark, add water.  If the test is too light add more tea, coffee or ink, making sure you change your notes.  You can use coffee and tea together for a variation on the color as tea has a light cinnamon color while coffee has a darker brown color.  Instant tea or coffee works just as well as brewed.  If you are using acrylic paint, remember that the fabric will dry stiffer; the more paint, the stiffer the fabric. Start with the smallest amount of paint and the most water that will still achieve the color you want.  Because of the stiffness, this method is best suited as brush on technique after the project is sewn.  Once you are satisfied with your test results, mix a larger batch of dye to complete your project, using the same mixture ratio of dye agent to water and leaving the fabric in the bath for the same length of time that you used in the test.

You may apply the dye by dipping the fabric in the bath, by putting the dye in a spray bottle and spaying it on for a blotchy, really old effect, or you can brush it on with a paint brush.  If you dye the fabric before sewing, the dye will be relatively even.  If you sew the seams and  dye the project before stuffing, the dye will be darker at the seams.  You can tie the fabric into little bunches before dying for a "tie dye" effect.  If you spray the dye on from a spray bottle, it will dry in spots, and the heavier you spray the more the spots and rings will overlap and the darker they will become. You have the largest degree of control if you brush it on.  Simply brush a little here and there where you want it and let it dry.  Continue brushing where you wish the heaviest accents to be and letting it dry between coats until it has the proper effect.  You can also add ring accents by dipping your finger into the tea bath and touch specific parts of your project, once it is dry.
