How to prevent cuffs from losing their elasticity?
I’m a big fan of half-zip sweaters. Over time, the cuffs invariably lose their elasticity, making otherwise-great sweaters unwearable.
There is an episode of Curb Your Enthusiasm in which Larry David claims that this is caused by rolling up the sleeve past the elbow. I am very careful not to do this, but the cuffs seem to loosen on me anyway. I fear it happens in the laundry.
Can anything be done to prevent or reverse this effect?
