Would somebody be so kind as to explain what "understitching" is? I am using an easy pattern to make a little girl's sun dress and the definition they give for understitch is as follows:
UNDERSTITCH: Open out facing or underside of garment; stitch to seam allowance close to seam.
I have read this sentence about 20 times yet I'm still not processing. I am at a step where I have just sewn the bodice lining to the bodice. Then it says "understitch lining as far as possible" Forgive my ignorance, but can somebody clarify this for me? In case it wasn't obvious, I'm a beginner when it comes to making clothing.
Thanks!
