What type of fabric should I use to make a case for sofa cushions to keep the cushions from getting dirty.
It would be nice if the cushion case can protect the cushions from liquid spills. But I don't see how this is possible unless I use a sheet of plastic. So, just protecting from light sweats is good enough.
The sofa has fabric upholstery (looks like very rough cotton) and has 3 identical seating cushions.
