in regards to storing fabrics in or on shelves, clear containers out and about in a room where they are exposed to light on a daily basis..
doesn't accumulated light fade the edges exposed to the light so much ??

Yes it does cause fading. The sunlight doesn't get on my fabrics unless they are on my machine desk.

Yes, light will fade fabrics quickly. I keep mine in a closet on shelves and in totes. I never open the window blinds unless the closet doors doors are closed.

I believe I've heard the same thing. I think in plastic containers the fabric would have more protection. However, on a shelve even in indirect light I was told the fabric would fade. All my fabric is kept in oak cabinets. Most of the fabric stores here have tinted windows to keep out the light.

I use the colored plastic totes. Black or dark blue.

All my fabrics on on shelves and no direct sunlight.I have one window and there and I sit in front of it so I can look at while I sew. Since you go to Joann's so much, ROFL, you could use the 40% coupons on the colored plastic containers, I love them for projects too. ♥

I also keep mine in a closet with the door closed. I've seen the damage the sun can do to furniture, draperies, rugs, etc. and I now protect all my things as much as possible. (Although I'd really, really like to have a day full of sunshine about right now!)

mine are all behind sealed units; but I see so many pics posted where you know they are in the light exposure all the time.

Iam always concerned , even the manmade light will fade fabrics. I put sheets over my open shelves.... but its a bit of a pain ... but I think worth it.

I once bought a pack of fat quarters that had been near the window in a quilt shop. The edges were all faded and they couldn't be used. The shop happily exchanged them and didn't put fabric there anymore.
