You can also cut a few inches off a clear soda straw and slit it lengthwise.
Cut it at a slant so the part opposite the slit is longer.
Wrap it around a chopstick or skinnier woden dowel, so the longer part sticks out around 1/8th inch to 1/4"..
(You can whittle the tip of a chopstick down to get it smaller, for smaller seeds.)
Scotch-tape that length of soda starw to the chopstick so the pointed end sticks out just a little, like a tiny shovel.
The chopstick blocks the back of the straw tighly so seeds don't get wedged in.
Scoop up 1-3 seeds. You can pour out controlled numbers of seeds by rotating it so the longest part is no longer lowermost.
Bigger dowels, or a pencil, could make a measuring spoon for bigger seeds.
A bamboo skewer and a coffee stirred are the right size for dust-like seeds, but I have never seen a clear coffee stirrer. (It helps to be able to see through the straw.)
The price is right!
