Hey there people-

If you have a badly cupped board (across the width) don't despair,
there's potential for a whole bunch of butt-comfy stools there.

Just saw it into short lengths, a foot or so, add legs at each corner
and ails to hold it all together and you've got a collection of comfy
places to sit.

You need a bandsaw to cut the curves of the cupped board, that you've
traced on the rail material, but that's it.

Good summer arts and crafts show sale material :-)
