Hello, I'm kind of new here. But I need help on my DC Superheroes superman cape. I find that it's too long that it touches the ground even when he is standing upright. So I want to trim off a bit of the cape maybe just above his ankcle's. I could just use a knife. But just for precaution, I wanted to check with you guys first.
If'n you do need to sand it, start with a rough grade and work down to a fine one.
