I don’t do this, but I do hang items on the line inside out especially if dark colours or have motifs on, while it’s warmer weather as don’t want them to fade, one friend washes everything inside out before puts in washing machine, but surely they get washed correctly anyway whether inside out or not,
H1954 I sent duvet covers out to be ironed when I was looking after poorly husband. They came back with the plastic poppers flattened so no longer useable. I keep meaning to replace them with a zip or Velcro but, I never seem to get around to it. There are always more important things to do like gardening or reading.
