Hi, sounds simple enough, only 6 tiles! However, I'm tiling down to the basin and the back of the basin where the tiles will come down to is curved, so if I put the middle tile in the centre of the basin the tiles either side will not touch the basin at their outer edges (hope this makes sense!) and leave a gap of around 10mm between the tile and the basin. Any ideas how I can make a tidy job of this? Thanks
