Saying that every girl must learn to sew is totally ridiculous ive never heard such a crazy thing in my life!
You may as well say that every boy MUST learn plumbing and joinery and electricianry because thats whats always needed in a house! I mean COME ON!!!! Sewing isnt so easy you know! (i know from personal experience i learnt sewing in school and high school and sem and i STILL cant sew!!)so thank goodness for dressmakers!
