Tiling around an archway

[benjy]

Hi, I hope someone can help me solve the problem of tiling around an archway.
The arch is similiar to the one in your discussion thread and I am not sure what to use as a finisher,I know it was suggested that the plastic type is used but these are only available in 2.2 meters and I need at least ten foot is there a longer finisher available from somwhere ?

Thanks
