One old trick is to mix tiny seeds with sand. The idea seems to be to improve the chances of putting a seed down near another while reducing the chances of clumping them up.

Remember the movie Summersby with Richard Gere? He came back with an extremely tiny (but extremely expensive) amount of teeny tiny tobacco seeds. They mixed them with dry sand and then broadcast them is seedling flats to sprout. Don't remember? It was a bad movie anyways.

Park Seed has a seed dribbler at http://parkseed.com/pro-hand-seeder/p/06528/

Burpee has a cheaper and simpler version at http://www.burpee.com/seed-starting/handy-seed-sower-prod001219.html?omn2pd=bz&catId=cat230002&trail=

Or you could hold the seeds on a folded piece of contrasting paper that makes it easier to mete them out carefully.

Thanks for your kind suggestions... I'll look into them.
