I have been dragging individual vertices from the outer edges in to the inner edge and merging them. There must be a faster way to sort of collapse the outer edges in to the inner edges. I will be working on more complex shapes and doing it like this is gonna take a lot of time. Hoping there is a faster way. Below on the bottom right of the image, you can see what I am trying to do. Taper it from the bottom till sharp on the inner edge. I need to do this all the way round.
