Do you read the Two Nerdy History Girls? You should, because they have great stuff. Example 1 is this post on double rings, a jewelry trend right now which is not new at all.
Also, from their links: Victorian Commons, which is profiling the members of Parliament between 1832 and 1868.
Also also from their links: Nourishing Death’s post on Swedish funeral candy. Perhaps some enterprising funeral home could reignite this trend.

This video from Digg shows a machine making drop candy as they did in ye olden days. It’s sort of mesmerizing.
