Frog Fastenings are sometimes referred to as a ‘Chinese frog’. These are ornamental braidings used to fasten the front of a garment and consist of a button on one side, with a loop to pass through on the other. The ‘frogs’ stand out eitherside like bookends. The fastenings date all the way back to Ancient China, but were famously used in in the brocade down the front of 17th century military uniforms. It was then that this decorative technique became known as ‘frogging’.
