Work a lot with silk and leather. Something about the union of such seemingly opposite materials. Along the way, found this great fusible interface made of wool/goat hair. This product transforms soft handed limp silk into a form similar to a bendable thin card stock if you will.
One simply irons the two materials and all of the crystals melt into the silk forming a bond. There is no fear of bleeding or alteration of the original fabric. Really amazing stuff. Usually us silk as lining in purse clutches, and this provides body and weight to the silks. Also prevents puckering/sagging of the silk.
Have used it on leather before, but it didn't work that well. Imagine a skived leather would have worked better, but wouldn't trust it not to peel.
For serious/large projects, fahsionsewingsupply will fuse materials for you in a professional press.

Silk: https://www.moodfabrics.com - Mood has designer fabric from many of the major fashion houses. Located in Los Angeles, California USA, they don't have them on their website, but to go in person they have floor to ceiling fabric options, many of which are not on the website. This print was $70 US per yard and is an original Alexander McQueen print from, what I understand to be, the 'Plato's Atlantis' collection.
If you don't mind, would you like to share a picture of any finished project using silk? just to see how it looks. Thanks!
