Hey, can anyone answer this question? I have a stairwell that had a railing from the landing to the top and now we are removing the railing and extending the wall up to 40" with a railing protruding from it. We stripped the drywall cap off and now we're framing the extension. I'd like to hang the drywall on the angle since it's most of 1.5 sheets. Is that angle going to tape out well? or should I be tearing the drywall back to horizontal and have a series of joints with the drywall cut off on an angle at the top?
