Alignment of Posts
Q: My playroom has a right post and a left post, but they are at a wide slant to each other.
A: Even if the doorposts are greatly out of alignment with each other, if a lintel connects them on their top, a mezuzah should be placed. However, if there is no lintel connecting them, and the ceiling merely flows from one room to the other, your playroom would be exempt from a mezuzah.
