Mine is white with lots of red pieces. I like it because my fabrics stand out and my eyes aren't drawn to the walls. I added a huge red and white french message board in front of my favorite machine where I post my latest ideas and artwork from the kiddos. Other than that, I'm surrounded by fabric. Life is good!
If not a white or off white, maybe your favorite color...or you could always bring in favorite colors with accessories. =)
