The best hand drying solution would have been the old-time cloth rotating towel machine. Or the new Dyson fast drying systems for home use. Dyson has been getting credit for these machines, but they have been around in Europe for a while. At $1400, it's not an option for home use.
I was thinking about sewing the leading edges of the towel together to make a loop. Maybe buttons would help with getting it on and off the towel bar. But I nixed that idea. I just folded Toftbo on the bar, showcasing the great IKEA colors.
