I started out with a plain round craft mirror and some macrame cord. I searched around for design ideas for the mirror that I wanted to create, and used that as a guide for my DIY. The design that I chose involved a larger oval shape, with a smaller identical oval shape inside of it, and straight pieces in between this pattern. The first step was to estimate the size of each piece of rope that I would be using. So, I took my macrame cord and placed it on top of the mirror to eyeball the length that looked good to me.
