Neil TileTastic

iam doing a conservatory and the 2 walls at bothsides are running in a angle and i was wondering what way would be the best to make the tiles to do these cutz, at the min i just lay all my tiles then use a paper template the same size as the tile to get the shape of the angle then i cut the template and place it on the tile and then cut the tile, but there must be a better way to do it as it takes a bit of a while doin it this way,

many thanx neil
