I ended up yanking it off with pliers and repositioning it!
Painted Vader's silver nose so the mask painting is now done. Still a lot of work to do inside the most difficult of which will be the fabric lining getting the pattern to follow the correct direction with no creases. I've tried test fitting a dozen times and it is impossible.
No I found something close but I screwed it up so I've ordered another close enough one. How the hell it is fitted is beyond me. It must be stretchy like t-shirt fabric or else I can't see any way of not getting creases.
The zig zag / herringbone weave will mak e up into lovely trousers, shorts and skirts, jackets, or a lovely dress with body. Adds to the designer look of this fabric. FIBRE CO NTENT: Cotton / Polyester.
