Marking clothes in a household with several people
Short answer: Put a small mark at the neck or in the waistband with initials or a colour code. Then nobody ends up hunting for their own socks.
When it is necessary
If several people of the same size live in one household, the laundry mixes however carefully it is sorted beforehand. A mark taking three seconds per garment solves it for good.
The two methods that work
A fabric pen at the neck or a thread in a particular colour sewn into the waistband. The thread method lasts better than pen, which fades after many washes. See bamboo underwear for men.
Socks are the biggest problem
Socks are what get mixed most often. Buy different colours for each person, or sew a coloured thread into the cuff. See bamboo socks for men and all bamboo socks for women.
Frequently asked questions
Does fabric pen survive washing
Partly. It fades after twenty to thirty washes and has to be refreshed.
Where should the mark sit
Somewhere it is not visible and does not chafe, meaning at the neck or inside the waistband.
Are colour codes better than initials
For socks yes, because you see them faster when sorting.
