So, any of you tried postwork on WSF material? Can it be painted by acrilic paints, or oil-based paints? Can the uneven surface be sanded or its too flexible? Can it be carved, cut, can it be scratched with a hot needle for example to create small grooves? Any insight on the matter is welcome! If you have done any of the above or any other way of postwork, I´m interested to hear about it!
