Boil 1 pint of water and pour it into a glass bowl with five teabags. Allow it to stand for 15 minutes.
Soak the Aida fabric in cool water while the teabags are steeping.
Squeeze the teabags in the water with the wooden spoon, and then remove the teabags and discard them.
Squeeze the water gently from the Aida, and then place the Aida in the tea dye. Give it a stir to evenly distribute the color, then leave it to stand for between 20 minutes to one hour.
Fill a second container with 1 gallon of water and add 1/2 cup of white vinegar.
Place the dyed Aida in the vinegar solution and allow it to soak for 15 minutes.
Rinse the Aida in clean water, squeeze it gently to remove the excess water, then lay it flat on an ironing board or other flat surface and block it out to make sure there are no distortions. Gently press the Aida until it is dry.
