how to prevent fading

[fiirmoth]

In all honesty, I hate direct sunlight in general, so when I bought my house, I bought one where I have no windows on the East or West side of my house so I get zero direct sunlight. Aside from that, My "Collectibles" stay in one room and that room has dark sun proof blinds. Sun is definitely the enemy. I would honestly say keep all Sunlight out of the room where your collection is. If that isnt possible, then the UV film is probably a great idea. If nothing else, keep the shades pulled during the day when the sun is most intense and open it during the evening when it isnt as bad.
