Beeswax hearts
Early American wax ornaments (without the wick for candle burning) were created by pouring melted beeswax into ornately carved cookie boards (very much like the ones used today for shortbread cookies.) Oftentimes the wax castings would then be painted to resemble cookies and hung for display. This tradition was brought to America by early German settlers.
Although figural candles are far more common in American folk traditions like hoodoo for conjuring, there are still some uses for small wax tokens as their use spans back through European traditions.
100% beeswax hearts
I cast my hearts from 100% beeswax. As you can see I tied a few to card stock with gold ribbon for use as ornaments (the hearts themselves are about one inch across.)
These hearts can be carved with symbols and initials, melted (or put on ice), painted, wrapped, rubbed or smashed– I guess it all depends on the goal of the conjure.
Personally, I like having a few in my sewing box to smooth threads.
