I've been sewing for a LONG time but when I recently bit the bullet and bought some very expensive fabric used in a show to replicate that costume, I was totally nervous about those first cuts. In the end, I had a friend come over and we ran through things together and then I started cutting. Annnnnnd....after all of that I cut it wrong. Turns out the pattern on the real costume is upside down. Thankfully because I'm a hobbit it all worked out in the end and you can't tell that I made that mistake. And then I made all kinds of mistakes on the jacket but you know what? People still loved it and I was still proud.
Long story short, experience and practice always help, but even with lots of experience we still are all afraid of new things. Failing though just isn't the end of the world, even though it may feel like it for a short while. I'd much rather try and fail than to never push myself to go bigger. I always try to remember that even though I look at all of the costumers out there who are WAY more talented than I, there are just as many people that feel I'm better than they are. Even after you're first attempt, you're still that one step ahead of the person who never tries.
