Sounds like a lot of fiddly fabrics to deal with. Nice work on using the selvage at the sleeves. And yes, it will be pretty!
I hadn't given much thought as to how I was going to deal with hemming my sleeves which are sheer AND embroidered with spangles - what a nightmare! I went through three different solutions before I finally hit on one that worked and didn;t involved painstakingly de-spangling part of the fabric then doing a rolled hem.
