Diagonal color change

Usually granny square consists of loads of colorful yarns that are changed after each row. But I propose a different approach!
Lets change the color in the corner ... so you would get a granny square that looks like this, or that, or ... ;)

And of course you remember the fun and colorful lacy granny squares from my last post ..

Remember: this is a real scheme for an idea! or a tip of how it could be done..
The most important part here is the corners where two colors meet, if you get the scheme of the corner you will be able to make most of squares with a diagonal color change ;) so good luck and have fun!

This will work for squares who has full corners because next row has to hide the other color in the corner of previous row.

Happy crafting!
