I haven't had much actual sewing time lately, what with my sewing machine troubles and the childbirth classes and the apartment-decluttering rampage. But! I finally got some time in yesterday morning and finished my endless rows of shirring. (Which, as Heather discovered, can be a SLOW, BORING and PAINFUL process--sorry Heather!)
The above image is what it looked like after I attached the two skirts together at the waist. I just have to tack them together and hem it now. AND I'm happy to report the stretch fit is perfect--it looks just like my sketch, and should still work post-preggo, too.
