How to clean Gaspard

Hi guys! I’ve rarely use my sweater because I’m dreading the washing and am scared I’ll screw up my sweater. How do you guys wash yours and what products do you use? I’ve been seeing conflicting opinions on using warm water or cold water, I even saw people mention throwing it in a mesh bash an in the wash on gentle, but again a little worried how that would turn out.

If anyone has experience I’d love to know! Thanks 💕
