So I have discovered that where I have my collection in the house my familey moved I moved into that the sun shines right onto my collection from about 1pm to about 3 pm. Now I know that fadding and yellowing can take a while. So I am not worried about the couple of weeks that they have been exposed. but what I have started to do is cover my two display casses and shelf with sheets before I go to work and then uncover them when I get home. This tends to a pain in the a$$ Does anybody know if they make a tint I can stick on the windows that will allow the light to come in but block the UVA/UVB?? Moving my collection is not an option.. Curtains would also be hard to do, the windows are set really high on the wall.
