This pin offered vintage soft t-shirts in only three days; unfortunately, it didn’t deliver on its promise of cuddly clothes.
I used a 100% cotton t-shirt that I rarely wear, because it just isn’t soft enough for my liking. I followed the brining recipe (from Octane) to the letter, soaked my shirt for three and a half days and laundered it as directed. While it did discolor it a bit in choice spots, I’m not sure it actually softened it at all — and certainly nowhere near vintage.
In my opinion, t-shirt brining is a bust.
