How do you sew with an iron?
Well, here is what I mean. See how much work I did on this lining before I attached it to the dress that I am currently sewing. The seams are pressed open, and the bottom hem that will be hand-stitched at the waist is pressed under 1/2 of an inch. I even pressed under the center back seam near the zipper. That will help me when I sew in the lining and when I hand-stitch the lining near the zipper.
I also added a strip of lightweight interfacing along all the dress top seam, even though the pattern that I used didn't mention that step. That interfacing will give that area some extra strength when I sew on a button for the straps. It will also give me some more body and a firm edge when I later add some topstitching.
So that's why I say that I'm sewing with my iron.
