Wash or wet the fabric. Remove the tea bags and add the fabric. Soak the fabric in the tea for at least an hour.
The fabric that you’re dyeing should be wet when you dye it. Wash pre-used fabric to remove any stains or dirt. If you’re using new fabric, rinse it in water before dyeing. Be sure to wring out the fabric before dyeing it.  Tea dyeing will only work on natural fibers, such as cotton, silk, linen, and wool. It won't work on synthetic fabric, such as polyester. While you should wring out the fabric before dyeing it, don’t allow it to dry completely. When your tea has reached the desired color, carefully lift all of the tea bags from the water and discard them. Place the wet fabric in the tea water, making sure that it’s completely submerged.  It may help to swirl the fabric around with a wooden spoon or other stirring instrument to ensure that it rests at the bottom of the pot and completely under the water. Some areas of the fabric may start popping up in the water. Use other spoons or kitchen tools to hold the fabric down. Once all of the fabric is submerged in the tea bath, allow it to soak for at least 60 minutes. Keep in mind that the longer that you leave the fabric in the tea, the darker it will be dyed.  To ensure that the fabric is dyed a very noticeable color, you may want to soak in the tea overnight. It’s a good idea to gently stir or agitate the fabric in the tea bath every so often while it’s soaking. That will help ensure that it dyes evenly. You can lift the fabric out of the tea at regular intervals to see how dark it has become. However, be aware that the fabric will dry lighter than it appears when wet so you may need to continue soaking it longer than you might think.
