From official page:

“Miroir” means mirror. Using lamé thread that reflects light like a mirror, we’ve created a yarn with flowers in it. Regardless of the season, if you intertwine this with other yarns, you’ll finish your fabric with sparkling flowers sprinkled on it. Also, you can create a perfect spring/summer piece with just one crochet hook thanks to the crispness of the lamé. Medium-fine thickness.
