I don't know about you, but it is always a challenge for me to keep my cross stitch kits and supplies organized so that I can easily find things while working. Here are a few ideas to manage your supplies more efficiently:

•  Use a large binder with loose leaf floss insert pages (these may be purchased at any craft store) to manage your floss. Start with the lowest DMC number and arrange all cards of floss by increasing number.
• When keeping floss on the skein, you can also purchase fabric pouches and organize them by color or by DMC floss number.

• If you have numerous kits that were started by not finished (who doesn't??), keep all pictures and directions together (a file cabinet with hanging files works great) but lay the partially stitched fabric flat in a drawer
• Kit management -- Pull out all the colors you need for the current kit you are working on and use a plastic sectioned storage box only for the colors you need in that kit.  It's much quicker to find what you're looking for when stitching.
• Inventory your colors.  Keeping an ongoing shopping list of colors as you run out of them or periodically checking for floss colors that you run low on saves time in the end.  There is nothing worse than sitting down to stitch and realizing that you are missing necessary colors.
• Label, label, label!  Whether you buy your own supplies or purchase kits with floss included, label your remaining colors so next time you need that particular color, it will be clearly marked and at your fingertips.  Consider that different dye lots produce different shades of color.  Start with a new skein if you will use much of the same color.
• And my golden rule:  If it takes longer than a minute to untangle it, THROW IT AWAY and start fresh!
