<div>You could sand the cork surface with sandpaper on a piece of
glass to get it straight.</div>
<div><br></div>
<div>Use the rounded edges down for sanding broad surfaces and the
square edges</div>
<div>for getting into inside corners.</div>

<div>My blocks are made from 3/4' plexiglass blocks. Some are faced
(1/4 sheet sized)</div>
<div>with back rail cloth for taking down the surfaces primarily. The
rest are faced with</div>
<div>bushing cloth. These don't warp.</div>
