What's the worst thing that could happen?? I've had a needle break off in my finger, sliced the tip off another finger, become so frustrated with a project that I rolled it into a ball and took it out to the trash can. I'm still a quilter.
Are you afraid the end product won't look good? Consider it a learning experience, keep it on a high shelf and move on to the next project, which will undoubtedly be better. (If anyone finds it, tell them that's what it's supposed to look like.)
An excellent way to learn is by making small projects. Consider making some children's quilts and giving them to charity. They are a superb way of learning new techniques and the recipients will be delighted with them. If you don't think you're up to making children's quilts, make some really small ones and take them to your nearest shelter. The recipients will think you are the most skilled quilter ever.
In any event, just do it. Before you know it, people will be calling you a quilter.
