For our flag’s colours here’s a dyed t-shirt. First you take a white shirt and tie it with yarn where you want the fabric to stay white. Pull the fabric, tie yarn around it and you’ll get a round shape. Repeat until you’re satisfied. Then you do what the dye colour package says: add the textile(s) and colour and start the laundry machine. The end result will be a surprise. Feels like Christmas to open the package! Cotton and other natural fibers dye the best. Here I was lucky because the thread was also made of cotton. Stains may not dye evenly which is good to know if you use preloved items.
