As per the title, I need to expand an area of tiling into a new extension and want to match up the tiles. The original ones I have laid are Mexican Saltillo bought about 17 years ago from a now defunct local store. I’ve looked at all the local ones and even thought I could get away with a standard terracotta, but on getting the sample from Fired Earth, that’s not going to work. To complicate matters I need 30x30cm as the design was laid diagonally and anything even slightly different in size won’t fit well. I can find Saltillo in the UK at 15x15cm and 20x20cm and I can even find 30x30cm from the US but not the UK. There’s one company advertising in Wiltshire but they are either shut due to Covid or closed down as the phone goes dead and no answer to emails. Any ideas anyone?
