I wondered the same. Maybe zigzag the seams or two rows of stitching would help? If it doesn't last terribly long, that's OK. I hope it compensates in efficiency for what it lacks in longevity. I won't invest a whole lot of time in its construction.
I came up with this idea when I stepped away from the kitchen sink with no towel available. I grabbed the torn linen shirt and, before I could wipe my hands, the crumpled shirt had already drunk up all the water on my hands. I like that efficiency.
I'd like to make the towel so that there are raw edges on both sides, so a quick grab of the towel produces dried-off hands. That's the idea anyway.
