Like Bob said, using something like large spotted pattern with a small opaque
area will make the marks less dense. Another trick is to combine several layers
of the pattern, at somewhat different scales. This will help avoid the 'regular
randomness' effect where the marks are placed randomly, but still at roughly
regular intervals.
