Sound cobblers to me. Knots that shrink just fall out.

Waroing is simply caused by differential expansion of the wood, and is
almost inevitable with crap like Pine.

that occurs too, but most often pine bends at a knot due to
differential expansion of knot vs the rest of the wood. But bear in
mind only a minority of knots cause warping, most never do.

Unless you carefully select quarter sawn planks (which don't actully
look good grain wise) you wll get warping between summer and winter
humidity levels.

not with pine indoors.

The reaosn teh victorians paibnted pine is because its crap. It moves,
it has knots that bleed resin, requiring knottong to be applied,

only needed if youre painting it, and it looks far nicer clear
varnished.


Ther is only ONE reason people use pine, and thats cos its cheap and
grows fast.

and looks absolutely lovely! - as long as you dont stain it.
