OK. So I went to SS today and spent a decent amount of time looking through fabrics they have available. The guy I worked with, one of their MTM specialists, was friendly, knowledgeable, and fun to work with.
To be honest, it's really difficult picking out a color from a small square of fabric. It's really hard to tell which is black, which is blue, etc. Once I began to get the hang of it, though, I found a few possibilities. I never hit something that made me think I found THE one, but I did come some good options, and they might actually be exactly what I am looking for color-wise, I just might not know it. The fabrics I was looking at were mostly by Ariston, though there were also some by Vitale Barberis.
Although I don't know if they had this fabric, my post-visit search of Ariston and Midnight Blue came up with these pictures. What do others think of this. Still too blue?
