In order to keep down delivery costs, paintings are sent mounted but not framed.

If you wish to frame your picture yourself, a range of simple, well-made frames at very reasonable prices is available from a UK eBay shop - 'Kraftybay'. Search for 'picture frame' in the 'Crafts' category, and they should come up.

Alternatively, Ikea do some good simple frames in A3 and other sizes.

For those not familiar with 'A' sizes, A3 is approx. 16"x12", and A4 approx. 12"x8".
