These Sketchdemao Evil Summoning hoodies are super easy to use. Just put them on and you're good to go! When it comes to washing, use cold water and turn them inside out. Wash them with clothes of the same color. Only use non - chlorine bleach if really needed. After washing, you can either hang them to dry for the best look or tumble dry on a cool or low - heat setting. But don't use fabric softener because it might make the colors fade. And remember, don't iron or dry clean these hoodies to keep them in good shape.
