Do you just ball them up and put in freezer? I like the idea of this approach, just need to make sure I do it right!There’s definitely a difference in quality of threads used in many brands.
I freeze my jumpers and jeans for two days rather than keeping on washing them after every wear. Probably wash them every third wear. It freshens then up without damaging the threads too much from the washing machine plus I rotate a lot so don’t wear things out too much.
