For you bags of floss, what I did was punch a hole in each bag and put the bags on a large metal separating ring. I use small zip lock bags. That way they are all in one place and you can take out only what you want. I keep the whole ring in a cute little "suitcase" box that has a handle and clasp. I also keep my embroidery needles in there too. The box is only approx 14" x 9 " so it fits nicely on a shelf but is too small to hold my embroidery hoops. I also write on the outside of the bags with a permanent marker for quick identification.

I made a holder similar to selm except used two of the metal rings and made several sets of bags on rings. I use one large set to hold all my floss in color order and the others to hold floss for particular projects. I take half of an index card, write the name of the project on it and put one of the rings thru the card to mark which project each subset of bags belongs to. [ATTACH=CONFIG]363960[/ATTACH]

For a small project, you can use snack size ziplock baggies. For storing laces, trims and lots of other sewing items, this setup would be highly effective. I use it for my scraps to sort by color, but it can adapt to any kind of supplies. This is two sets of storage drawers on wheels attached to a top with double sided tape. Between the two sets of drawers is just enough room for stacking the plastic shoe box size containers. [ATTACH=CONFIG]363962[/ATTACH]
The top can be used as a cutting table, a surface to stack more storage drawers on, a book shelf or any other number of things.

One other storage idea I use that serves a double purpose is my storage/seam pressing table. It is small and handy to the right of my sewing desk yet on wheels to move away when I am not using it. No construction is needed as the little portable ironing board fit exactly over the shoebox size rolling storage drawer cabinet, and the ironing board legs hold it in place. If I need access to the top drawer, it is a simple matter to lift the very lightweight ironing board aside.[ATTACH=CONFIG]363965[/ATTACH] [ATTACH=CONFIG]363966[/ATTACH]
