Cretan Stitch with Shisha Mirror

For the Take a Stitch Tuesday Facebook group I'm in, the challenge for this week was the Cretan Stitch.  I found a tutorial online for using it to secure a Shisha mirror, something I've always wanted to learn how to do.  I tried it once years ago and got nothing but frustrated.  This tutorial helped me quite a bit.  https://www.needlenthread.com/2015/01/stitch-fun-shisha-embroidery-with-cretan-stitch.html
