Help, I was very pleased with my new ceramic floor tiles with nice rustic looking wiggly edges, but just how do I lay them properly? I have a long straight edge to set the tiles against, but I don't know what to use to keep the space between the tiles equal as normal tile spacers won't work. Do I need to get a very large right-angle thingy, or perhaps buy long strips of very thin wood and cut up!? What do the professionals do? Thanks in anticipation, Rita
