Hey!
We've just started renovating a house from 1929. I was thinking of replacing the old tongue and groove in the ceiling with drywall. Now that I've pulled everything down, I realize I don't quite know how to join the existing drywall with the new ones. As you can see in the pictures below, the finish isn't completely straight.
How can I solve this most smoothly without having to drywall the entire room?
Regards,
Carl
