Coursing/bonding of my tiles

[Unregistered]

I have a vertical strip of tiling either end of my bath which 3 tiles wide made up of 0.98 x 0.98cm tiles like that of a mosiac strip. My problem is the tiles i wish to join up to them are 30 x 10cm tiles thus every tile is gaining 2mm putting it out of bond.
Anyone know a solution to this or where i can get 30 x 0.98cm tiles as i cannot change the 0.98cm tiles.
Thanks

Just a quick one for you! Are they porcelain tiles and if so, you could have them cut and polished on the edges in a decent tile shop!
Good Luck!
