English: Washed cloth was hooked on to the Tenter Hooks, and the bottom row of hooks released to stretch the cloth as it dried in he sun and wind before further processing. These are believed to be the last remaining Tenter Frames in the world and these frames date back to the early eighteenth century. From this method of stretching the cloth the expression was created: 'To be on tenter hooks'. (Description copied from adjacent signage.)
