Fila satin wax - thanks for the suggestion. Does it need removing and reapplying when it wears? How does it change the appearance?
PJC - most of them have only one decent face, so cutting would be a waste of time. And TBH an expense I can do without, on a very tight budget. I looked at your brick slips a while ago - very nice. I'd love to find a place to use them here, but again, funds don't allow. I should have been a rich mans daughter!
Rainsco - the photo doesn't do the colours justice. I'll try to get a more accurate one tomorrow.
