No-one likes general adverts, and ours hadn't been updated for ages, so we're having a clear-out and a change round to make the new ones useful to you. These new adverts bring in a small amount to help pay for the board and keep it free for you to use, so please do use them whenever you can, Let our links help you find great books on glass or a new piece for your collection. Thank you for supporting the Board.
