Tiling's easy dude. Make sure the surface your tiling onto is clean and smooth. What sort of wall are your tiling onto? You may need to put some plywood up if its an old house, to keep everything in-line. Batons are important. level it all up like you would with anything, Dont put too much grout on, only 3-4 layers of tiles at a time too. I find it easier to not leave the spacers in the wall, just put one edge in, then move up a layer. Keep the tiles clean! this is probebly the most important part. Constantly sponge off excess on the tiles or it dry's shit. Not sure what else to say really. Get your self a decent tile cutter, and float with a good size edge, to put the grout on with. make sure you keep all the lines in the grout going the same way, and push the tiles into the wall. Leave the tiles over night before you grout them. Just keep everything clean and dry. Good luck
