Follow the layout by installing loose tiles along with their spacers all the way to the walls.
Wall tiles fitting process.
Use a saw tile to cut a tile to fit around an awkward shape such as a pipe or architrave.
Prepare the surface.
If necessary repeat this step along the intersecting center line for a precise design.
Mosaic tile can be laid directly on plywood or wallboard in non wet locations but cement board offers the best underlayment and is the preferred.
During the wall tile installation process you will likely need to cut some tiles to fit.
Tile cutting jigs are inexpensive and are much easier to use than freehand tile cutters.
If the gap between the last tile and the wall is greater than 1 2 tile then adjust the tiles to one side or another.
If the cuts needed are smaller than half of a tile you can adjust the center line by snapping a new line a half tile size closer to the wall.

You can make straight cuts on tiles with a manual tile cutter or a tile wet saw.
Use tile nippers for curved cuts.
Nippers create rough edges that you can smooth somewhat with 80 grit sandpaper.
As with any tile installation the surface for mosaic tile must be perfectly flat and smooth.
In modern tile work the underlayment is generally cement board applied over a plywood subfloor or directly against wall studs.
Cut the tiles to fit into any gaps.
