I need a wide tip one that is permanent. i have loads of the Pigma pens .05 and .01. do they make a wider one? what i want to do is make black lines on fabric before i cut it that will be permanent. the fabric that has this is expensive and only comes in 1/2 yd cuts. So i want to make my own then cut triangles or diamonds out. I am doing a test with scraps and a sharpie but doubt it will stay well over time.
