Crochet Gif Tutorials: The Foundation Chain / Foundation Single Crochet
The Foundation Chain is an alternative to the starting chain. It makes the starting chain, and a row of sc’s, all in one go. It can be tricky to pick up, but once you’ve mastered it you probably wont go back to the old method! I like it because it gives you a better indication of the finished size of your project, and it’s stretchy!
