@anoh While "the pillow-case has been resolved", that chairs left armrest (right for us readers) is probably also lacking a line. You can see it on the other side, and in the first panel (with male guy in the chair) you can see weak traces of it. The spiral is the wood being carved decoratively, not the fluff on the armrest somehow spiraling through 4 dimensions.
edit: should this be @amplified?
