Hey guys, new to the forum.. I'm currently tiling a bathroom and have the tiles cut around the window in the front wall.. I've tried my hardest to get the edge of the window tiles as straight as can be but when placing a tile edge trim up against the line there's a 1mm gap every now and then.. As in its not quite 100 percent a straight line.. I'm planning on using a tile file when dried tomorrow but just wondered if there is something I could of done different.. I've tried using a sanding stone but it'd take me an age to sand off 1mm.. Is it normal to have a 'slight' grout edge on the flush trim and will it be really noticeable if so? Diy'er but a perfectionist so I want it to be as perfect as possible.. Thanks š
