Wim;
 In my opinion it is the swelling of the wood which causes the 'tight' center 
and not any swelling of the felt.
  In response to my own question I have laid out on a grid..actually the Ola 
Rotary cutter board :-)... several different thicknesses and widths and types 
of felt. I measured, cut,  and placed them on exact lines. I have soaked them 
so that they are moist but not wringing wet. I am going to leave them there 
overnight to allow any "swelling" to happen and measure them again in the 
morning.....I'll letcha know.
