Quick note on errata for the Sew What! Skirts book: If you have or borrow this book, and the instructions for the 1/2-circle wrap say to divide the waist measurement by 6, it is wrong - you divide by 3 (approximating pi). Later versions of the book correct this, I understand. I found the corrections from helpful on-line sewists.
Hey! I just realized why many persons who sew refer to themselves as "sewists" rather than "sewers."
I also just realized that this skirt, laid out on the carpet, looks a lot like my Christmas tree skirt, only in blue/green/brown calico.

And now just for fun, go to this 2008 post from Posy Gets Cozy and read all the way, including the comments. You'll laugh! Her next newer post after this one had wrap skirts, and I found it helpful. It tells me I need to let my skirt hang overnight before joining the 2 halves at the hemline. Don't know if I can stand to wait.
