This is a simple tutorial on how to crochet a reversible granny square. The instructions are tailored especially for left-handed people but the tutorial can be used by right-handed people too. If you're right handed, all you need to do is work a mirror image of my actions shown in the video.
The benefit of working a reversible granny square is that you finish up with a perfectly even square. If you make a granny square in the traditional way, it tends to lean over to one side, and you won't get flat edges either!
This tutorial is suitable for beginners, as it only requires the use of chain and treble stitches. Enjoy!
