I am working on a bridesmaid dress order with Dupioni Silk. I love working with silk but it's SO delicate! I didn't pre-wash this silk because it's dry clean only and I really didn't want to change the drape - it's natural color so there wont be color running issues and I really wanted to keep the crispness of the fabric.
I usually pin the fabric with super sharp pins on the seam allowance but I found some mini cloth pins (they're about 3/4" long) I used on a display last year and they are amazing! I might start using them on all my delicates - especially jersey. I ran a pin through my serger last year and ruined the timing. It took two weeks to get my machine fixed.
For the lining I'm using 100% lightweight cotton lining fabric. I'm about halfway done with this order and I can't wait to see the final result!
