What my brother and I did in his house. (He had a older house where nothing was actually square. ) We taped off the molding with that blue painters tape and then used some drywall mud to help "blend" the places where the moldings did touch.
We let this dry and then just repainted the ceiling where we patched it. It was a little time consuming, but it definitely looks a 100% better now. Hope this helps You can also use a nice quality paintable caulk to fill in the gaps.It looks great when finished.
In later periods, when carpenters and other craftsmen built houses from cutting the timber through the finishing touches, they made all the moldings for the building, including crown moldings, on-site, choosing the wood, cutting, sanding, and carving it, and finally giving it a protective finish and installing it. In some places, plaster workers crafted crown moldings out of that material as well. Since they were extremely labor-intensive to produce, such decorative touches usually were options only for the well-to-do.
With the advent of machines that could mass-produce moldings, the products became common ornamental elements in even modest homes. Crown moldings in particular began to grace homes all over the world. Admirers of older architectural styles value homes with original crown moldings in place for their beauty and authenticity.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
