These are two that have helped me.
The dog tooth method ( that I learnt on here ) has been really handy, particularly with mosaic.
I also got shown the ‘Flip’ method, put tile you’re wanting to cut face to the wall, Mark on the back where cut is to be made. Flip the tile back towards you, transfer marks to face of tile, cut. And it fits perfect, comes in handy for cutting first course in, I’ve used it a lot( most probably use laser level now, and start with first course, I don’t have one yet)
Probably teaching a granny how to suck eggs with these, but I like them.
