Kome,
yeah, last time i ever heard from my mum, when she was alive, and my sisters. but i understand that as long as u dun use sharp objects or do sewing in your bedroom, especially on the bed. should be fine. my colleagues also say as long as not on the bed, it's ok.
seriously, the old folks will say no sewing, no cutting, etc. but if we cannot do all these, then anything torn or when we have to cut some fraying threads from our clothes, how?
