We have a large batch of rectangular handmade terracotta tiles on sale (previously £6 per tile) at £2 per tile. Measuring 310mm x 200mm (with some variation), they would make a fabulous rustic hearth, or even a kitchen floor. We have plenty of them.
Also available at the same price per tile (previously £4.50) are 8" x 8" (200mmx 200mm) 'rusty' slates - characterful grey slate riven with red layers, and irregular pale grey tiles. All at £2 each, while stocks last.
