dear, can you tell me what it's called, the paper that some use in multicolor embroidery seems to, but at the time, gloss, thanks!

thanks!

And well before Mylar there was something called rainbow paper that one needed to iron onto the embroidery, from memory.

Mylar. My neice sent me some. I am going to sew something with it this week.

My guess would be mylar - as well.

Is it mylar? Some designs are made with open spaces, where you can stitch a piece of mylar inside and it gives a neat shimmer, kind of irredescent glow. They are fun!
