I've been carrying Aquis or MSR ultralite towels to roll my knits in (Current pieces in question are a swing cardigan and a matte jersey dress) to aid with the drying. I also always wear an underlayer such as a silk T or cotton T. However, I tend to find myself in stinky situations such as smokey (kitchen or even second hand smoke) where simple airing-out doesn't quite work.
As most of my travel wardrobe is black-based, hotel towels leave white lint all over everything where even a good lint brush or tape doesn't remove everything (hence bringing my own towels).
I would love it if hotels would offer an option of black towels like how good restaurants offer black napkins.
I'm going to try the blocking thing again now that the weather is cooler and the knit is denser/tighter weave. Will report back
