Planning but no sewing

It's been a while since I last posted but I'm still here. After having MS (multiple sclerosis) for half my life, one would think I'd figure out how to stay in front of it which actually I usually can do but this time, I can't seem to beat the fatigue which has me falling to sleep on the couch or when I go to cuddle with my boys at bedtime for a few minutes and waking up 4 hours later. So although I have three UFO's that I need to finish and a new pattern traced and altered and fabric pre-shrunk, I cannot seem to stay awake to do anything. I also have all the major components for my dedicated sewing area purchased (table, rolling task chair, Ott light (40% off at JoAnn's), I don't have the energy to put the space together. I haven't even been viewing the PR digests and keeping up with blog posts daily which is unheard of! Hopefully if I go to bed early for the next two nights, I'll have enough energy to make a simple top on Friday.

Finally, a perfect invisible zipper . . . or so I thought

So one of my projects for this year is to learn how to perfectly insert an invisible zipper. I stayed away from the evil things for years but everytime I see one in someone else's garment, I promise I'm going to learn to do this myself. After a few false starts with either getting the zipper twisted or having it not really be invisible at all, I finally did it.

A proud moment indeed -- that is until this happened.

This is what happens when I sit, bend or otherwise move in the skirt. I think part of it has to do with the fabric being a stretch suiting but do you have any other ideas about why this is happening?
