Here are some of the places my research and imagination have visited recently:
The world of medieval Pater Noster cords. How do they differ from rosaries? Both are used to count prayers, but rosaries form a loop, while Pater Noster cords hang loose at each end.

(14th century reliquary from Florence, Italy)
And St Edburg (also known as St Edburga or St Eadburh)
