I love these. I will admit, I did not go online and watch the tutorial. It's pretty self explanatory. You get some (awesome) adhesive and all the pieces and parts, all you need to provide is some creativity and, maybe, some tweezers if you don't have the steadiest hands. I made mine mirror reflections of each other and had a blast doing it. Love the way they look, they are comfortable to wear, and classy looking! I will be ordering a pair for my mom for Christmas and likely more of their products as well.
