I did my own with some red fuzzy material. It isn't quite velour like the grey stock stuff, but not suede either.
Its not hard really, just take off the seat cover, use a razor blade to cut the threads holding the various panels of the cover together, and either make new panel from scratch or glue on material onto the panels and resew to cover back together. You'll need a fairly stout sewing machine and needle if the fabric is thicker.
