I didn't get quite as much done today as I had hoped but still, I had respectable progress. I serge-finished the hem and vent edges. The back vent is complete. And I sewed the side seams, so the skirt is all one unit now! I also pinked the side and center back seams. The skirt is now ready for hemming.
The lining is ready to be sewn up and attached to the skirt (I had to buy ecru thread so that held me up). I've also looked at the vent lining instructions so I'm ready to tackle that little chore once I've hemmed the skirt.
