Finished!
I had the day off today and spent it finishing the skirt. Bride had not lost all of the weight gain so I had to let it out to use the smallish seam allowance. I backed the seams off with cotton bias to give a little strength as the satin frays like a demon. Supposed to be silk but it wasn't - it was from a shop in the Goldhawk Road, so be careful if you're down that way - take some matches and do a burn test outside!
Anyway, all done a draw string bag made too with a lace outer layer.
Glad it's finished and hope you like it. I created a train effect by cutting the lace on the fold and on bias and then box pleating at the waistline, and making a small slot in the lace at the zip.
