How do you dry things flat?

[Jemster]

I've ruined some of my clothes by not following the washing instructions properly so am trying to change this.
Some of my things say dry flat but I'm not sure of the best way to do this. What should I lie them on?

On a towel in the airing cupboard

I lay them over the top bit if the clothes horse and just drape things carefully, that might stretch if they're allowed to dangle iyswim.

I've got a flat rack that fits over the bath & use that for jumpers etc.

You can buy flat drying racks. I have an Ikea Algot thingon the wall.

I have a mesh thing that pops out flat and folds away like a tent. It lies over the bath or showEr.

On an airer that has a flat rack on top. I only have 1 so can only wash one dry flat thing at a time! :)
Actually can dry more if carefully placed over the airer at an angle.
