Trying to DIY a new interior door on a bedroom for the 1st time ever. After some initial chiseling and sanding, I hung it and it closed, was a little tight but closed. A few days later, now it’s rubbing on the hinge side against the lip of the molding in the middle of the door, and on the other side where the lock pokes out the side, it’s like it’s too wide somehow so i can’t close the door. If i’m standing outside the room and push in on the side in the middle of the door on the hinge side, that “eliminates” the rubbing on the hinge side in the middle. Do i just keep sanding down both sides until it closes? or just in the middle? or is it something else?
