Not sure which forum.... assuming this is a non-load bearing wall, I'm not sure what frame is required for a small pass-through window. Are jack studs required? Or even an entire frame for the pass-through? In other words, can the bottom sill plate simply be nailed onto the bottom cripple studs and toe-nailed into the full side studs, and the same on the top? It doesn't seem the wall really needs to support anything, after all. That seems pretty flimsy though.
