Yes, I guess you could say I have lots of experience. I've been knitting since I was 8-years-old, which is over 50 years.
I have also developed some efficient ways of doing things. Such as knitting BOTH the front and back at the same time on my needles, using two skeins of yarn. I do the same thing with the sleeves. This allows me to make sure my tension and gauge are the same and makes it easier for me to pay attention to the directions ONCE. I have learned how to to increase/decrease at the end of a row in a manner that is very smooth and, nearly, invisible. This is especially important when making garments.
I am also a very quick knitter. When I was in high school, I made sweaters for extra money. It wasn't unusual for me to make a sweater per week in my spare time. Guess I'm slowing down.
I'm only knitting a sweater every two weeks.
