I have 3 Billy bookcases (two, with doors on the lower half, are in my "office" to hold genealogy and other notebooks and office supplies) and one I've just recently bought to hold my quilting supplies: fabric (on comic boards), notebooks, fat quarters, etc. That one has full length doors, the top of which is glass.
I love Billy bookcases because the shelves, though made of MDF, are so much stronger than the bookcases from Wal-Mart, etc. Also the Billy bookcases are taller.
I've been happy with everything I've bought at IKEA (including a 2 cup glass measuring cup that looked like a laboratory beaker. Loved the thing but it was fragile and soon broke. Have never been able to find another one). They currently have some little plastic rectangular bins (no tops) that are strong and heavy and not expensive. Bought 4 of those; two large and 2 small, for miscellaneous quilting supplies/fabric.
