There is different advice about the best interfacing to use to stabilize the fabric from silk ties. The silk is flimsy and on the bias. Dave of Dave's Craft Room said he used the stabilizer that he used when sewing a t-shirt quilt. I don't exactly know what he used, but a ultralight weight knit interfacing is often recommended for t-shirt quilts. I used Pellon White Easy Knit Fusible EK130 for the top piece. And it is very light weight and slippery. It is a good weight in general, but was very slippery to sew.
The bottom interfacing is Pellon Featherweight Fusible (911FW). It is stiffer than what I wanted, but it is much easier to sew. I would not want to hand quilt it, and the hand of silk isn't really there anymore. But given that I will want to have some precision with seam intersections, this will be my choice for the project I am planning.
For the test I am trying flip triangle corners. The top row has the knit interfacing and the bottom has "featherweight" that we will call cardboard.
Using the knit interfacing is a bit like wrestling eels dipped in oil. And using the cardboard gives the satisfaction of origami.
