I’ve found that you have to feather / blend the homax can texture a good ways out into the wall to hide patches. In my experience it helps to soak the can in warm (not hot!) water before use to get a finer spray pattern, ymmv. Usually that + a quick knock-down w/ a drywall knife or a quick sand after, and I’ve been able to decently match the “orange peel” of our 1930s plaster doing repairs or even adding new drywall walls and wanting them to appear original.
