I cannot do paper piecing. I've tried and tried and have finally given up. That's why I will probably never do a New York Beauty.
Most of the things I probably won't make isn't because I can't but just because I am not fond of the pattern. I won't make a double wedding ring. I also probably won't ever do something with a lot of hand applique because hand sewing is so hard for me. I have done some machine applique tho. Generally speaking, if I really like a pattern I will probably try to make it. My first experience with curves was because my daughter loved the pattern and asked me to make it for her. It wasn't perfect, but she loved it.
