What i do is cut a peace of plastic to a L shape, to a depth of the mosiac and the width of the border use rapid set fill the area and scrape off, when set fix border with rapid normally would tile up to border on all walls then when set tile up to ceiling.

Just an update, after finding I could only get the tile spacers mentioned by Rich online, which would take about 3 or 4 working days, (about 5 or 6 actual days because there was a weekend coming up), I did the mosaic along the second wall using a bed of tile cement. To make life easier, I cut a small piece of wood to shape so that I could level the tile cement at exactly the right depth (4mm below the surface) all the way along the wall (I screwed a 9mm strip of wood along the wall above the position of the mosaic so that the tool I made could be levelled on the tile surface below, and the strip of wood above). This worked well, except that I had to wait 2 days for the White Star to go hard before putting the mosaic up. I like JHeff's advice about using Wedi. If I can find that in the shops, might use it for the next wall. To avoid the delay in setting, I tried using finishing plaster for the same purpose in a few short lengths round the window alcove, but then was a bit dismayed by the advice on the tile cement to "let new plaster dry out for 4 weeks before tiling over" (!!!). Won't get on to the next wall for a few days, because now trying to solve problems putting a large heated mirror along the wall behind the basin.
