Excellent instructions from DogHouseMom. That being said, I like Ginghers lightweight scissors from JoAnn's. If you are right handed, then Gingher's dressmaker ones would be fine. I've had my lightweight black plastic handled ones for at least 20 years and they are still sharp. Until recently, I was a dedicated apparel sewer, so they have had heavy use.
Fiskars just don't hold an edge for me. I save those for fleece - do not cut fleece with your good scissors.
