Anyways, this is my first silk blouse. I have been terrified of tackling slippery fabrics and while it will take me a while to recover, I'm so glad I made it!
I used covered buttons, it seems like the right thing to do with this kind of garment. As well as doing French seams, quoting Trena "it's the right thing to do with silk". I serged the first pass and then enclosed the serged edge. Thanks Trena!
