I use the el-cheapo extra fine nibs from Hobby Lobby. I use the eyedropper(my new bottle has an eyedropper, the one in the picture doesn't) to put a drop of ink on the underside of my nib, then get things started by pulling the pen toward me with the nib on a piece of cardboard, this also gets rid of the excess ink.
I touch the nib to the bow to make a tiny dot and start writing. If you don't make this dot very often things won't flow right. I only make the dot on the first letter of the first line, it is unnecessary for the next line.
One pen load may not be enough to write several lines, it the pen starts to skip I reload it and go through the process again as necessary.
