Good practice for tiling is to buy a jigsaw and cut all the lugs off with scissors. Then insert the lugs into the inny bits , leaving you with card squares. This is just tiling in miniature. Alternatively, practice with scrabble tiles in a dolls house. Hope this helps.
If you want a course for tiling and can't do the full college route or shadow a tiler Nett in the South Shields is great.. If you check the tilers forums everyone recommends them.. Do a good two week course.. Went there last year to top up my skills as I work alongside a mate who's time served in the tiling ..
I run a weekly tiling course in my garage on a Sunday Morning, between 10.30am and 11.00am. This includes a 25 minute morning break. It is a comprehensive course which covers all aspects and types of tile, and is fully accredited to the LRGTF (Labrador Retriever Good Tiling Federation.
