A request for tutorial help came in on this blanket. This is the Ombre Corner to Corner C2C Blanket. The help request is about the border. I haven't done the preliminary background work yet but is added to my list to get through.
I am adding this to the list of projects on my website so I remember to back and do the homework to teach this. I expect to be covering this between now and April 2023.
Below is how to do corner-to-corner in either a square or rectangle.
Currently I am on a quest to learn more about corner to corner with attempting different combination stitches just for the fun of it. This is the Crochet Corner to Corner Criss Cross. A new tutorial is available as well to follow. Very fast to do.
