Going from the mistakes I made my first time, label all of your pieces! I picked a lot of seams my first time, and sewed at least one piece upside down.
Also, it’s a lot simpler if you use an easier fabric to work with. I made my first corset from cotton velvet, and it crawled around in my machine until I wanted to pull my hair out. My second corset was made from a cotton jacquard, and was SO MUCH easier.
If you have any questions while making it, feel free to ask. I’d love to help!
