You can cut the fabric with very little fraying and neat crisp cut lines. You could almost make a paper template as if you were making it from paper or card, with overlaps etc then cut the ProFinish cloth from the template and even pre-fold and crease the fabric so it fits in nicely. You might find a spray tack useful if it keeps springing away from the mould faces or tries to lift up.
