Care instructions: Wash it in cold water with similar colors to keep the black color vibrant. Avoid using bleach as it may damage the print. When drying, it's best to hang it up to prevent shrinking. Also, be careful when ironing; use a low - heat setting and avoid ironing directly over the print. If you notice any loose threads, you can gently trim them with scissors.
