I'd be annoyed about the cupboards too - but at this point I'd probably just hang the curtains and be done with them. If they've already been sent back to the seamstress and are still not right then it sounds to me like there's been miscommunication somewhere along the way. Then again, maybe she got a dud seamstress, since there's also a problem with the window seat. Maybe not, though, since somebody who works as a seamstress left a comment on her latest video telling her the window seat cushion is too big - and that's what's causing the problem.
