These will be perfect for protecting & keeping together both sheet sets & blankets on closet shelves. Some reviewers made me worry they'd be too thin/floppy, but they are just what I need. Quality seems very nice. After all, they're not supposed to be hard-sided storage boxes; they are soft- sided -- better to scrunch a little into a tight space if necessary. Attractive & neutral. Such a bargain, I got 4.
