At one time you could buy imported cottons that had a metallic thread running through them I think most were from India.
Piercing a metallic thread would probably leave a jagged edge which would fray fabric - I haven't seen any of these in over 30 years.
If the fabric is imported and used for special type garments like a sari or scarf, I'd see if I could find any hints about sewing and embroidery from the nation that produced them.
Otherwise - minimum quilting and more of the STID type straight line
