Brindle

Hi folks,

Have just tiled a small kitchen with 3" porcelain tiles. on 2 double sockets they worked out to be one tile at the top edge where I couldn't insert an edge of tile, as there was no surface to affix to.
Is there any cures for this? I started with full tile from worktop, and central to cooker hood so was down to luck where they landed really

Cheers guys
