I tried on the skirt with basted side seams. I can live with what I saw. I don't think the fit is bad, it's just that my body is really asymmetrical. I have a high hip on the right and a left hip that's so curvy in comparison, it may actually be a saddlebag. This has not dampened my spirits because I need some skirts!
Here's my fix to the back waist.
In my very brief sewing experience, I've decided I'd rather not thread elastic through a casing, if I can help it. I remembered that when I made a Kwik sew denim skirt before, I didn't have to. I dug the pattern out and tried to find an online tutorial to share with you. Deepika has written about the technique here.
I added Nancy Zieman's technique of zigzagging the ends of the elastic to a piece of fabric.
Lemme tell you where I went so wrong. Asymmetrical me requires separate front and back pieces, right? Cut them right side up on the right side of single-layer fabric. I did the same for the lining. This just ain't fair. I can't say I didn't know. I can say I didn't understand. It's the first thing Susan Khalje covers in the lining section of The Couture Dress. Now I get it -- clearly and painfully. Mirror image means flip something.
