The bow does look big but it must just be an illusion with the camera as it is just a standard 3 inches wide! The length (pre folded) was 30 inches long as the coach who ordered them wanted them that size! I usually make at 28 inches.
There is no 'standard' size here in the UK as such - some coaches believe 'The bigger the better' but I just make what is asked (within reason)!!
