Rules of Understitching
Rule #1: If you’re finishing an edge with a shaped or bias facings or applying a collar, then you cannot, must not skip understitching!
Rule #2: Prior to attaching a shaped facing, it is interfaced for added stability!
How to Understitch
It’s really not difficult, but you do have to take your time, so you can be precise!
And here’s how you do it…
Step 1: Staystitch the neckline and armholes of the garment and the shaped facing.
Step 2: Then, align the right side (RS) of the facing to the RS of the garment’s edge and stitch them together.
Step 3: Now, grade and clip SAs as needed before understitching.
Did you notice that the SA of the facing is graded in half?
Step 4: Press the SA up towards the facing from the RS of the garment.
Step 5: Then, from the RS, edgestitch the SAs to the facing. You want to position your needle very close to the seam, no more than ⅛ inch away. I like to find a spot on my presser foot to use as a guide to help me maintain the proper distance away from the seam line!
Take your time understitching, please!
Once you’ve completed understitching, this is how it looks closeup…
Step 6: Press the facing to the inside of your garment, rolling the RS of the garment ever so slightly towards the inside of the garment. This will be easier because of understitching!
And you’re done! Behold the finished result from the bodice side…
and now from the shaped facing side…
If you’ve done this right, your facing will hopefully have the good manners to know its place, which is INSIDE the garment!
