Sewing is one of the entertaining and useful art
It is indeed, I love to sew and ive made over 100 pieces of clothing in my years, What sort of things would you like to know about it? 
Oh, its great. What kind of clothes did you made?
Well, I love to craft and fasten buttons, I always use cross stitches with a needle and thread to make sure the threads dont break. .
Placing a thread inside a needle is a challenging job for people with any age.
Older people like to use a sewing machine to stitch fabric and other materials together because its much easier and no threading is required. 
Some of them has very powerful eyes. And they were very efficient in that.
Haha yea I know some older people who still have great eyesight, I know it can be hard to focus on something so small when you're old. 
Moreover, sewing is a must learn art for everyone
It sure is and sewing was done for thousands of years all by hand.
