  1. Pretty, but if you’re inclined to make something like these out of old circuit boards, you might want to be concerned about the lead in the solder. (newer circuits boards are more likely to be lead-free.)
    I can’t get a good reading on how dangerous skin-contact with lead and lead alloys is supposed to be. From some reports, you’d swear that gloves were a requirement for handling fishing sinkers…
