This is a simple one. I have the plastic tables you can get from Sam's club. They kind of suck for sorting because the shirts slide around and fall off sometimes. So this last week I took some old pallet tape and run a strip down the middle of the table and then coated it with water base adhesive and dried it with a heat gun. I also used some masking tape so the edges don't come up. It works really well and now they don't build up static like they did.
