The whole process of tin weaving is done as the following(reference from One Needle, One Thread):
1. stitch pattern with black thread on unmarked white cotton., back side up
2. turn over to inspect front side.
3. dye embroidered white cloth in indigo.
4. cut foil into strips of 1.5-2 centimeters wide
5. cut tips sharp and pointed in order to pass through embroidered stitch.
6. fold back tail end.
7. pick the stitch with needle to make room for metal strip.
8. pull metal strip through until it catches as tail.
9. cut strip close to the stitch.
10. crimp gimp closed to secure.

　For more information about this stitch, I highly recommend the book-One Needle written by Tomoko Torimaru, so far, this is the best book for Guizhou embroidery stitches, Tomoko Torimaru and her mother are the best field experts for Guizhou ethnic textiles.

This embroidery technique takes so much time and labor to finish, even a small piece of front or back apron, and now the labor price in the countryside is not cheap, so the price in the village is high now. For instance, it's about 500RMB for a front apron, sometimes it's much more expensive than some textile shops in Kaili or Beijing, because those vendors had collected the textiles some 20 or 30 years ago by paying maybe just 5-50 RMB for each and stored them to wait for a better price, so now they can sell them about 120-300RMB for each in the shops.　

　When I talked to some villagers in Raohao village, why I can't see people wear jackets made of tin weaving, they said it took so much time, now the young don't want to stay in the village, most of them like to go out to big cities to make money, so no one likes to continue this embroidery technique.
