I don't hide it 'cause then I'll forget what I have. All of my fabric is on boards and on shelves like books. My batting, interfacing, etc. is in plastic bins. I have, thanks to my late wonderful FIL, many cigar boxes and they are great for purse components, trim, elastic, etc. Rulers are on a belt organizer and I just, I'm so easy, bought four of those swivel storage dealy bobs for my large spools of thread. There is not enough room so navigating my sewing room is only for the brave or fully informed. It is one room where I am absolutely calm and happy so I'm keepin' it.
