Here’s a little trick I wish I had learned ages ago. I finally mastered it a couple years ago, and it has helped me tremendously. I use it for any project that begins with more than one stitch in the starting chain. I use it for triangular shawls, squares, circles, and triangles. It’s strong, and quite easy once you see it broken down properly.
Here’s a little slide show to break it down, and below that is a link to a video I made especially for this little tidbit.
Here’s the video if you need some verbal help and more of a breakdown.
