TR6 upholstery screws, washers

[Pete & Aprille Chadwell <dynamic@transport.com>]

Listers:

Is there anything particularly special about the little counter-sunk screws
and dished washers that are used to fasten upholstery panels in a TR6?
Should I be able to get these at a fabric store or someplace like that
locally, or would I need to order them from TRF to get screws that will
work?
