Hi there, I've done a couple of job's recently where the customer has wanted a horizontal mosaic border. Although the customer's have been pleased with the result I'm not! I'm a bit of a perfectionist and I'm looking for advice on fixing the mosaic (the 15 x 30mm type that come on a sheet approx 300mm sq). Next time I've decided I'm gonna set the room out and get some ally angle straight edges, screw to the walls and fix the mosaic's 1st and leave them overnight or 24 hrs and tile up to them - is this best practice? I'm sick of the odd wonky mosaic, dipping in or out, up or down!!
