Whenever possible, I like to keep bulk to a minimum in my sewing. So, I am finishing my coat hem with a bias self-facing (click on images for larger view):
I am using fusible interfacing in just the hem of the coat.
A 2" hem is given in the coat pattern, yet I shortened the pattern below the waistline so I can use just a 1/2" allowance at the bottom to turn the bias facing I will sew. I cut fusible interfacing on the bias about 3" wide so I can place it with the contours of the bottom edge of the coat. I also pieced it so it goes behind the seam allowances of the coat.
Here, the bias interfacing is pieced and overlapped 1/2":
The coat hem is now ready to be turned and pressed to fell the bias to the wrong side of the coat. On that note, I move to the inside of the coat. I will pin tuck and assemble the brocade lining the same as for the coat.
