One of the challenges in sewing in a lining of just about any sort, is that you really only have 2 kicks at the can. Oh sure, some people might be able to eke out 3 or 4 tries (I suspect the correct term for that is "eek"), but if you're working with a fabric that frays (charmeuse - I'm looking at you, bitch) or a zipper insertion, you're likely asking for trouble the first time you unpick.
Of course, when one beautifully sews a zipper into a lining, and then just as beautifully sews that into the outer garment only to find that the zip insertion in the lining is inside fucking out, well, then (s)he has no choice but to use up that second life-line.
Ask me how I know.
Now, let's add some fuel to this fire: Let's say that you originally used double-sided wonder tape to "baste" the zip to the lining. (On the first try, that works beautifully, fyi.) On the second go, after you've picked the stitches and the zipper off the lining and the double-sided tape stays seriously affixed to the frayish, floppy lining fabric, then you've got some issues. (Non-sewists: No technical skill is required to understand this scenario. Quite simply, it's a royal fuck-up.)
Word to the wise: At this point, throw out the original zipper. Give it to the sewing goddess and get a new one. Cuz if you flip the old one over (with some of that adhesive still stuck on that side), you're going to wreck a couple of needles and then - even when you get a nice-looking finish - the charmeuse is going to stick to the zipper in such a way that every time you try to open or close the fucking garment, the lining is going to get sucked into the teeth.
Cuz if you don't do it before you start the second insertion, you won't have another chance. And then your "looks pretty good" skirt with the zipper sandwiched (professional-like) between the lining and the fashion fabric will merely look good.
Personally, I prefer functional closures.
Now, if you'll excuse me, I'm going to drink something strong and eat an ice cream bar before dinner. More reflections on this suit are pending. And lots of shots, natch.
PS: I grabbed the camera to take some pics - I mean, it doesn't look
half-bad - but the kid (amateur photog that she is) burned out the
batteries again. So we'll have to wait till tomorrow for that.
