Okay so long story short, my 10.5 tog double duvet needs washing (says on the label it can be machine washed) however I’m not 100% sure it’ll fit in my washing machine, I’m tempted to take it to the laundrette but the machines there don’t have many settings and I don’t want to risk ruining my duvet by not having it on the right setting. Has anyone had any success with washing their duvets in their domestic machine?
