So as the title suggests for the life of me cannot get my head around this, i am trying to use Mask to reveal only parts of another layer by using Mask and then the brush tool. I am sure it is relatively easy but I just cannot get it to work (i use procreate as well and can peform this quite easily) See screen grab so for example i want to reveal only the central part of the E as indicated by the circle in green (this is obviously not part of the main image, purely to highlight the area i am trying to reveal on top of the red handwriiten letter)
