moisture in wool or wood. was Re: When to do it

[Richard Moody]

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.

    Wool, and presumibly felt, say did you use felt or felt cloth??, shrinks
when it dries.  Didn't your mother when she washed your wool sweater, pin it
to form on the guest room bed so that it would not be shrunken when it was
dry?  ---ric
