You take a pieces of black fabric and place shapwell under it (that is a material like stabiliser)
Cut up bits of threads or pull a glitz piece of fabric apart to get the threads. I used gold and silver as I was making badges for our upcoming Quilt show.
Cover with net pin and then stipple heavily over it.
I cut mine up into diamonds but you can do so much with this technique.
I will post another piece that is done with cut up bits of wool but instead of netting on top I put washaway. Opps will post that one later as I have only just dried it but I am posting one of it before I put the washaway on so you will get the idea.
Both ways work well.
