^ not really... I used to take my own brushes to school when I was a kid, because all the other kids in the classroom
left the brushes standing in the cup of water, which is the best way to ruin a perfectly good paintbrush in a matter of seconds.
that's why art supply stores sell big packages of paintbrushes crazy cheap - for kids:
Of course, if money is no object, as was the case when the nice lady wearing the fur coat came into Northwest Art Supply one afternoon when I was working in Dallas peddling pencils at Preston and Forrest Lane, then by all means go for the best.
She was just pleased as punch when I waltzed her out to her Continental and loaded $600 worth of Windsor Newton watercolors, Grumbacher brushes, and 400-pound hot press paper into the trunk for her 6-year-old granddaughter.
(That was November 1984 - feel free to adjust for inflation.)
More to the point: if we waited for every workman to own and use the finest quality, high-end tools, we'd never get anything done.
The Seattle Art Museum (in Volunteer Park) has the largest collection of vintage jade artifacts outside of mainland China. The tour guide explained to us that the intricate work done - carving those tiny shapes inside shapes inside shapes from a single piece of stone - was all done with no more than slivers of bamboo, sand, and water.
It's the Indian, not the arrow.
