A client wants me to make matching table pads for a table I've just completed, and I'd like to use a velvet-smooth felt for backing the pads. Anybody done something like this, and know a source? I know that woodworker's supply sells sheets of adhesive-backed felt....I'd just like to know that it wouldn't mar the table. The tabletop is sapele, topcoated with SW Sherwood moisture resistant lacquer, medium-rubbed sheen. The pads will be made out of 1/2" MDF-cored sapele.
Should I be concerned that once fully felt-backed, the pads could warp?
Thanks in advance.
