Hi daz
I was shown the way you are thinking at college, this was fine as yyou could get up and walk through the non existant walls
so first kitchen job, squared up , worked out cuts and laid the room in quarters as shown
first quarter fine tiled it out from centre, couldnt reach the cuts had to leave them
second quarter same with cuts but tiles no longer lined up with line struck on floor tiled it anyway
third quarter same , off line by a couple of mm
fourth quarter:yikes: didnt fit and never would
lesson learnt, lifted lot and spent afternoon cleaning and stacking tiles, cleaned addy off floor
had to think quick as the customer was due home, i told her the addy was duff and wasnt setting so i removed it in case it wasnt going to set properly
next day set out again working back in rows and cutting as i went, the job went well and i enjojed it
days money plus addy lost but a lesson well learnt
