I started using the flat flower head pins when making a OBW. I continue to use them for just about everything now though. I have discovered that there are different sizes of the pin shaft. I got a package as a gift and these are thicker, not so easy to use. They don't bend as easily however. I also have some glass headed pins that have a thin shaft but aren't as long as the flower head pins. These also are nice to use, especially if pressing over them - no chance of melting the head.
