The final round has dawned. It simply consists of one fabric, showing some stripes and a floral twirl.
The exciting thing, however, are the corners. They are mitered, which does not mean that a bishop is invested, but rather that the border strips meet diagonally. Therefore, I sewed the four border strips to the sides of the quilt top stopping short from the quilt corners. I pressed the seams and layed the quilt top right side up. Then I folded the border ends back forming a 45-degree-angle and pressed it.
Next, I sewed exactly along this crease and pressed the seam open.
I flipped the quilt right side up again to check if the angle line is accurate and the corner is flat and square.
Not till then, I trimmed the excess fabric.
This is how the finished corner looks like:
I did a mitered border for the first time and am very glad to say that I succeeded with all four corners at first try.
