Re: 10 sheets up!
Little farther today but Not a thing is square

. Thats life

. Just gotta work around it.
Oh man! That is gonna hurt!

You shoulda squared up the floor joists B4 the deck went down. Everything fits better when you are square and plumb.
Don't worry, it's all still do-able but you will have a little xtra work when you hang drywall.
Keep up the good work and good luck!
ps
I don't know your experience level so don't be insulted if I underestimate you, but when you need to square something measure length and width on each side so each is equal and then make sure the corner to corner (hypotenuse) distance is the same.
Or, 3-4-5 rule, 3 feet on one side, 4 feet on the other with a 5 foot diagonal.
