I have to admit I'm pretty concerned now regarding the wall. I had not planned on there being a back wall section. I thought that the "back wall" section was being taken up by a backdrop. I am wondering if a backdrop is 100% necessary now? Also I thought that a 72 inch wall would eat up one side (6 feet) as the dimensions to my knowledge were 6 feet x 9 feet.
I do not know when the latest dimensions of this were drawn up -

I'm concerned that if the wall is jagged like in the diagram, how will the tiles be laid out then, how would they follow that pattern? Somewhere I saw a picture in one of these threads that was a recent one that showed the approximate thickness of each section - I can't find the pic now, it was what I was going off of. I understood it to be that the actual wall was being converted into just one long strip.
My problem is that I can't just cut apart what I've done already into sections. I don't have the necessary tools to do so, and don't have the money to buy a nice saw, and if the walls have to be a perfect 45 degree angle on the cuts, I can't get that done right in time with what I have. I'm not a carpenter and did not foresee the wall to need such precision - I had thought that the wall could be modular all along, and that if it needed to be rearranged some it could be done on site.
I am either going to have to start the whole wall from scratch or see if someone can take this over. The insulation foam will not work for such a wall, it's just too fragile/no way that sharp angles can be made with it (and I have my doubts with foamcore as well). It looks like I've got a pretty big problem here because I have got to prioritize a baby coming first - I have worked on the wall now for at least 12 hours of time, and thought that I was close to having it nearly ready but now it looks like this is not the case... I have to get started on the baby room this weekend and I am getting carpet installed/finishing my basement next week, and am getting nervous as hell that I'm not going to have the wall to the standard that is wanted.
As for the thickness, what if the wall was only two inches thick, would that be ok?
- OR -
Could we modify it to look like this -

If I can modify it to be like the second diagram without all the angles, I can still get this done on time. If the angles need to be 45 degrees, I can tell you that I'm not going to be able to get it done correctly with what I have... If someone has a suggestion or an idea on what to do, please post your thoughts. I think that wood is the
best way to go with this, even though shipping what adds up to about a 14 foot wall is going to be tough.
Thank you!
