1st Shibori embroidery attempt

So, I've been in love with the colors of Shibori silk ribbon embroidery and have wanted to give it a try. By the yard it's just so expensive for me and it's a big commitment to a color to buy a yard, I felt. I was happy to find it on etsy by the half yard, so I could buy two colors! I wanted to make a cuff originally but didn't have any blanks for the base and was worried he silk would get wrecked from wear. So, I made this brooch instead and think it may be a retirement present for my mother in law.
