What is an Otterburn?

In the late 19th and early 20th century, the heavy rugs which kept people warm when travelling in stage coaches, open top cars and trains were called Otterburns. Mr Wallace, the local postmaster, sketched Otterburn Mill in 1908 to advertise the Otterburn rugs which were being given as accessories on the new Rolls Royce cars.

To be on Tenter Hooks, why?

This famous expression came from the textile trade. Otterburn Mill boasts the last set of Tenter frames in Europe. After cloth had been woven it needed to be washed and dried. The drying process was done on the Tenter frames by hooking the cloth onto the top and bottom bars of Tenter hooks and the bottom bar was released to stretch the cloth.
