I have been putting my new mono speedy in the sunlight in a sunny room. My boys room is especially sunny in the afternoon so I put it on the dresser in the early part of the day and then the sun moves to my older one's bed and I set the bag on his bed for the latter part of the afternoon. I rotate the bag every half hour or so, lol so both sides get exposure. I only did this for one day so I don't know if it's working yet. I seriously don't want to wear it the way it looks now, too white, I don't like the looks of it at all, wish it would get a slight golden hue.
