I am really stupid when it comes to tiling out jobs for walls with corners. My brain just cant think straight when there is a mural that needs to go around a corner or double back. I have learned to leave 2" bleed on all sides and to overlap corners with 2". My problem is the math, I get so confused trying to keep it straight in my head. Where should one tile end and where the other begin, taking away 2" here and overlapping 2" there. ughhhh it ties my brain in knots. To be honest I dont even know how to ask the question. Maybe I am making it harder than it needs to be? Are there any apps that automate/ help lay out the big jobs for rooms with corners and weird spots to go over and around? Feel free to just call me an idiot here, but if anyone does know a simple equation or an app, maybe there is a corner option in Onyx I am missing???
