I've been hunting literally for a sking of sky blue or darker plain blue
15 cm tile to no avail. Although I did find one tile specialist on the corner of an industrial estate who could order them for £1.01 each!!! even he said it was dear for a plain blue tile.I've tried all the usual, B&Q, Homebase (like they ever have anything :) ) ... topps tiles, tile giant ...
If anyone has spotted any around london anywhere I'd love a kick in the right direction chaps
Cheers
