My desk is one of those foldable outdoor desks(pic below) and I really don't like how rough it is. I was thinking of getting a yoga mat to cover it with but my friend said it's a bit sticky and I won't be able to use my mouse although I was planning to use it with a mousepad anyway. I'm trying to figure out what material to cover it with and I've never really seen anything else that's less than $20 that I want to use.
I was looking at antistatic mats(way out of budget); desk mats(out of budget too); and even cloth(which will probably be really bad).
Can anyone help? What should I wrap my desk top of? I'd like to have it smooth enough that it's almost like glass maybe.
