Oh i might just quickly add that i am not saying course trained tilers are no good but in my time of doing it i do not know of one other course trained tiler who became good off the back of what they learned on a course. They became good after learning from proper tilers and putting in tonnes and tonnes of hard graft and loss of earnings whilst they learnt this trade. The trouble is that their are a lot of people who do these courses as a free bee if they are on jobseekers allowance or benefits etc and they turn into a big waste of space and ruin the industry (not in all cases of course). But those who paid for it themselves have a bit more at stake so are more determined to make it work and to do whatever it takes to make it work.
I must stress that all this is my opinion and i have formed this opinion from my personal experience. Nd i can honestly say that if it weren't for Andrew at Cambridge
Tile and Mosaic (he's not on here nut does have a website if your interested) i would never have got to this stage.
