Scenario:
I have my foam attached to an upholstery needle which is chucked in my dremel. I'm using an emery board to shape.
Question:
On some bodies I'm developing a crease while shaping. Does this mean I'm using too high of a speed? I'm thinking the heat generated, along with too much pressure from me, is cause this.
Or, do I need to switch to a finer sandpaper?
Thanks,
Bruce
