I ended up piecing the front of the hem to fix the length issue. (I love that piecing is period!) It took quite a bit of brain wattage to get the fabric I needed out of the small baggie of scraps I had left from this project. So glad I haden't thrown anything away yet! Luckily I was able to use some of the pieces I had to cut off the back section of the hem to shape it correctly. Whew!
After all that piecing the hem is a bit of a mess up close/underneath (so nobody gets to see it!) but with the "3 foot rule" applied it's fine. Eventually I'll finish the inside with bias tape and add some ribbon or trim to the hem to cover the horizontal piecing seam but that is a project for after CosCol. I have many other time-consuming and more important fish to fry in the next 15 days!
With another dress moved to the "done" list I'm feeling much less panicky and stressed, although I know I can't slow my pace at this point. So I've officially started my pre-CosCol TV fast - no TV until I get home from LA! I miss it already but I get SO much more done without it to distract and waylay me. And with my to-do list I need all the time I can get!
