Generally speaking images (which can be of any size) can be mounted on any suitable board but must not exceed 400mm x 500mm in dimension. In competitions mosts people use white, off white or black boards.
Mount card can be bought in various sizes from art shops or ordered on-line. The nearest supplier to the club room is the Range in Newport Road which provides sizes up to A3.
Pictures can be surface mounted (no cutting involved) or window mounted which involves cutting out a window to ‘frame’ the image. Some companies will cut out ‘windows’ for a small charge. Cotswold Mounts provide an excellent service and provide colour samples free of charge.
