I think I hit a stopping point on the garage today. I rounded the corner and the tile mosaic now goes from the door jamb completely around one side. I think that I will grout this can consider it done for the season. If I get some nice weather, I will do more but as it stands now, I am not counting on it. When I do the grouting, I'll give a complete technical description of everything I did, just in case there are other insane people out there that want to try a similar project.
