Speaker covers

I have a multi-purpose room that also serves as my audio room.   It gets a lot of light and opening, closing numerous shades daily is not practical.   Speakers grill do not typically offer 100% UV protection.    I don’t want my speakers damaged over time given UV.   So I went to a craft and fabric store and picked up some thick, soft material.   Connecting with a lady who will sew some custom speaker covers that will cover the top and front of the speakers and attach using velcro tabs.   Has anyone else done something similar?
