I've been doing a little bit of organizing lately. Now, this is just a very small drop in a rather large bucket, but at least it's a start!
I've been using and collecting embroidery floss for several years now, and have never had a consistent place to keep it. As a result, I have little caches of thread all over the place. There will be a baggie with some threads in a drawer, some more in with my crazy quilting supplies, some more in a tote bag with a project, etc. That makes it hard to find a particular color of thread when I'm looking for it.
So these little floss bobbins came to my rescue. The bobbins and the box into which they fit so nicely. I've gotten quite a few of my thread skeins wrapped and "filed," as you can see. I'm separating them into sections of reds, purples, blues, greens, etc. Look in the upper right-hand corner of the box in the top photo. Those are all black thread. All. Black. Because I couldn't find the floss I needed, I was constantly having to buy more black thread. There doesn't seem to be any variation in the black hues, either.
At first I was a little leery of letting go of those little labels with the color numbers on the skeins. But I've never been one to follow those numbers anyway. If a pattern calls for "DMC 346 pink," I just find a pink in my thread stash that I think will look good in the pattern. So I let go of that worry. I think the advantage of having all my thread organized, and all in one place, easy to see and easy to choose will win out over not having their DMC numbers available.
