Here I have laid out the pieces I need for my lining.
Because most lining fabric has no give in it at all and often a wool or twill weave will stretch a bit, I always sew my lining with 1/2" seams while the outside of the coat is sewn with 5/8" seam. This gives the lining that little bit of ease that is good to have.
Here is a series of photos showing how I did this.
Notice that the fold of the pattern is placed about 1 1/2" away from the fold of the fabric. All good lining patterns have a center back pleat to allow for movement and, again, that little extra that makes for a good fitting lining.
Take your ruler again and mark a new cutting line 5/8" inside that stitching line just marked on the back pattern.
To not damage the back pattern, use a tracing wheel and transfer paper to mark this line onto the lining fabric.
Here is the new cutting line, with the added pleat next to it. I will be stitching where that pin is for about 3" after that top part is cut away.
Stay stitch and clip this opening so ...
A lot of clipping, trimming and grading of seams needs to be done. And then the coat should be turned right side out and pressed well.
Do the same with the sleeves, sewing the seam allowances at the armhole. This is the only place you DON'T want the seam allowance opened up. The seam allowance from the sleeve and the coat should be pressed outward. It isn't possible to sew completely around the armhole. Sew as far down each side from the shoulder seam as possible.
Next, smooth out the front facing, which is in this case is the same pattern as the center front panel of the coat and pin it down.
Please let me know if any of this is confusing. I hope that this makes it possible for everyone to make a lining for any coat.
