After I published the post yesterday I realized the corner triangle can just be 2 of the setting triangles sewn together. Two of them will be like this where the rows join and corners are formed. I will have to sew 2 triangles together for the others.
This is one of the corners that they will be sewn onto.
Did anybody question that block at the top that looks like it is going the wrong way? It is the beginning of the next round of shimmering triangles and it doesn't look right turned the other way either. I could have made 4 blocks that were 3/4 dark and 1/4 light and it would have been a perfect fit, but I like the quirkiness of it the way it is. Check yesterday's post for the whole picture.
