What makes it "impractical in this day and age". My wife and her mother knitted sweaters, cardigans, scarves, hats. My wife also sewed skirts, blouses, and full length winter coats. I don't have any hand knitted skirts but I do have several that were commercially machine knitted. I'm quite sure that had my wife wanted to she could have knitted and sewn many complete suits of clothes.
