After years of observation, it has come to my attention that most beaders do not prefer this method of beading. This is interesting to me, because the beads speak to me so much more clearly when they play together like this. I see color combinations I might not have thought of, I'm am visually pleased as I work. I love these little palettes laying about the studio.
Back in my freeform days I always mixed the beads which I thought had many advantages, portability being one of them. I could put all of the beads in one container, rather then stopping to put them all back in their own little correct container.
The other bonus of working from this pile is that I have a built in 'repair kit' when I'm done. I just spoon the remainder of the palette in a baggie and toss it in the drawer. If I ever do have a failure it would likely be years from now, when I'd have no idea how to find the correct bead.
I've come to realize I'm in the minority, but old habits are hard to break....
