Lucky you; they sound fascinating!

I don't know how things work where you live, but in the past when I've needed something restored, I've gone to an art gallery.  We have an excellent art gallery where I live that even if they can't do the restoration work themselves they know all the people who can.  I once took in a 100 year old painting to be cleaned and restored and there were people in there who had brought in some old embroidery samplers and the art gallery people were telling them they could send the samplers away on their behalf to the right people who did such delicate work.  The art gallery people were also saying the samplers would need to be remounted with acid-free cardboard as cardboard that's not acid-free can damage old fabrics too.  Heh, sometimes it pays to eavesdrop on other peoples conversations, LOL!

I would suggest getting the work done professionally even though it can be expensive (and take months and months to do) but its worth it in the end.  If that's not an option, don't try to do too much yourself,  just keep them out of direct sunlight and away from damp.

Hope this helps a bit and good luck with your project!
