This fused glass heart featuring stripes in the order of the transgender flag is made from frit (crushed glass). While each one I make is a little different in the width of the stripes perhaps, they all contain the same colors in the same order, and you probably won’t be able to tell if you receive the exact one in the photos or not.
Please don’t use a suction cup to hang them in your window; A ribbon over the curtain rod or a small hook in the window header will work much better.
