To make a beautiful inlay that is not fragile, we use a reinforcement of angles.

Step 1: reinforcement

First, you need to sew your lining rectangle diagonally, then you scallop to the seam and oversew.

Step 2: assembly

Now, you will have to assemble your two parts, being careful not to prick the lining. Once you get to the corner, just let your needle stick and then lift the presser foot and rotate the fabric.

Step 3: finishes.

After sewing, you must iron your assembly and cut the reinforcement to reconstitute the angle.
