I made this for my sister and she wanted jean material. You will need a heavy duty machine, my machine is supose to be able to sew threw 10 layers of denuim and I had to whip out my heavy duty needle and my apholstery thread to sew about half of this because of how thick some of the areas were.
I had to put material over the top of the jean material so that the silver spots would not melt so I could get the PFF to iron on. Will never use material with this on it again.
the spots are silver
