I also used French seams on the lining, and it frayed so easily, that the outside was a little furry. After trimming all the loose ends off the first seam, I trimmed the rest to 1/8 inch before sewing right sides together.
I cut the lining shorter than the shell and the hem the usual amount, which did not want to press well. From now on I need to finish silk with a narrow hem.
So that's it for summer sewing 2017. Not much, huh? I've made a few other things this fall. (I'll probably post those in January.) So I guess that leaves me with two goals for 2018: trying to sew as many garments as possible throughout spring, including summer clothes, and accepting that the weather is just too lovely to get much done June through October.
