Using this Sketchdemao 'Welcome to My Lair' crewneck sweatshirt is super easy. Just put it on and feel the comfort! When it's time to clean, remember to machine wash it cold, turn it inside out and wash with clothes of similar colors. If it gets dirty and needs a bit of a bleach, use non - chlorine bleach. After washing, you can either hang it up to dry for the best shape or tumble dry on a cool or low - heat setting. But don't use fabric softener because it might make the colors fade. And don't try to iron it or take it to the dry cleaner, as that could damage the fabric. With these simple steps, your sweatshirt will stay in great condition for a long time.
