I think it is up to the person. We are all sinners saved by grace.. If one says not to sew on a Sunday then maybe that is their conviction. Is it any different than watching some of the things another will watch on TV? Is it any different than cooking a meal? Were we meant to sit and fold our hands on a Sunday??? I believe your answer is in your heart. If you feel the Lord nudging you not to then for you maybe you shouldn't. Same as one eats pork and another feels it's a sin. I do not know where you are spiritually, I say take it to the Lord and follow his will in YOUR life... No man can judge....many HUGS :)
