3.5 hours is a long time. I think the only thing that might shrink them some more would be a hot soak, like boiling hot water soak. Notice: you won't want to be in the tub with the jeans on when you do this. Luckily I didn't lose very much indigo at all in the cold soak. I'm thinking of soaking them tomorrow and just wear them around right now for the rest of the night. Anything wrong with this? I guess I should be doing squats or something. (pre-soak). I'll take post- tomorrow because the lighting sucks here (no flash).
