I need help from some fiber artists / quilters / sewists...
My wife has a hand embroidered satin (maybe its silk or more likely its some kind of blend but it feels satiny) blanket from when she lived in Japan as a kid.
It's a satin + batting + satin blanket with a binding made of the same satin material
This blanket is old, and we'll worn, and we'll loved, and has tears in both the seams themselves and holes in the fabric itself. As well as spots where the batting has worn away / is missing.
I know how to hand sew but I have never sewn anything more delicate than a cotton quilt. I have also never mended a hole that is not on a seam.
How do I
1) repair the holes in the batting? (I was thinking some kind of needle felting to attach patches but... idk if that's how that works)
2) repair the holes in the satin that aren't at the seams in a way that reinforces the fabric without noticeably changing the texture of the blanket? (I was thinking about lining the inside of the hole with a cotton amd heat interfacing or something and then sewing the layers together and close the hole but then... this blanket has to be able to go in the washer and dryer and I don't know what that would do to the interfacing)
And bonus
3) if I need to source new fabric for the holes, how can I tell what the fabric is?
