Equipment: one sunny living room, one clothes airer (as wide as a t-shirt), no pegs (they leave marks, and I do not iron).

1. turn outerwear inside-out when getting undressed and wash it inside-out, it will save it from damage during washing and fading during drying;
2. t-shirts on airer first, inside-out, folded across the chest just under armpits
3. then briefs, one per airer length, which leaves enough room for
4. two socks per length next to each brief, folded across the middle lengthwise
5. jeans over two airer bars, to distribute weight and avoid discoloration if dark and new-ish
6. jumpers over two or three airer bars, same reason as 5
7. shirts on hangers on side of airer.

I flatten things a bit by shaking them before hanging them, and then again a bit when I fold them to put them away, and that’s it. I only iron a shirt very rarely if I really need to wear one.
