Last week I was in need of drywall tape. I never made it to Home Depot myself, so hubby got me some last week! I applied it along the edge of the ceiling, along the crack, then spread joint compound over it. After letting the compound dry for a few days, I sanded it down smooth. Then I applied another layer of joint compound. Once that’s dry, I’ll sand it down and will probably have to apply a 3rd touch-up coat since I can still see a bit of the tape.
