Margo, your Challenge 3 is exposing my dirty little secret. I have been keeping my sewing space really neat and organized since I went through it last spring and redid everything. I refolded all my fabric, moved things around so it all made better sense, got bins and boxes for storage, etc.
However, I have two drawers that I haven't been able to face - one contains beads and assorted surface embellishments I collected and haven't found quite the use for yet and the other has embroidery floss and all of my miscellaneous non-quilting notions (zippers, trim, etc.) most of which I will probably never use, but you never know. Having now looked in the mirror and admitted my shortcomings, I will have to act decisively. I guess that's why I have what seems like 1000 empty Altoids boxes. I've been saving them for, you guessed it, those two pesky drawers.
