I have to start by confessing that I have directional issues, so I may have messed up and will appreciate correction as long as it comes from a person who is not similarly challenged!
If you look at the corners you’ll see the leaves are slanted in different directions. This is how I chose to orient my leaves. You can choose a different orientation, just be aware that the A and B leaf pattern instructions are different from each other. Make sure you choose the right color(s) for the correct corners.
