I just finished a pair of socks using a very beautiful red/purple/blue yarn that was dyed by my LYS. Past experience with their yarn when washing is that the darker colors bleed and darken the lighter colors. I don't want this to happen to these socks b/c the red is so vibrant.
I remember reading somewhere that you could add salt to the wash water to stop color bleeding.
Anyone heard of this or have other ideas to prevent color bleeding?
