Is there some webbing stuff I can use to I take up these trousers please?

Hi. Not sure where to put this thread. DS has trousers which I will need to take up but I'm hoping there's some product which will allow me to let them down againwhen washing them (so they don't get a line) and then put them back up. Not sure such a thing even exists but any help gratefully received! TIA.

Won't that be a complete PITA to do every single time? And I would think they would get a line anyway, as you'll find the crease and keep putting it in the same place? Even when washed things will re-crease in the same place after a while.

Wonderweb it irons on & I have found it lasts a few months though can easily be taken down again

Thanks very much.
