The key to a successful online order is to measure your pictures accurately prior to completing your order. Make sure you are measuring in cm if the frame sizes are listed in cm. Once a frame is made it cannot be cut down to a smaller size and there is absolutely no way that it can be made larger!

If you are after a cheap certificate frame I would suggest that you ask your local picture framer to knock up a ready frame from off-cut mouldings.
