I agree with ManiacQuilter2. As long as you are satisfied with your results, you are good to go. You do need to use fine pins so you don't move the fabric when you pin. Also, from garment construction, we were taught to pin on the table like the video. Don't hold the piece up in your hand. I usually pin with the head to the left, even though I'm right handed. I also occasionally use the Sally Collins method and pin parallel to the seam, like Holice does. I do this with a really complicated block.
