I don't use a single camo pattern at any time. For example, today on stand I actually used 6 patterns at once, I had the old military eastern woodland pants, my bug suit top, my harness vest, my gloves, snake boot,and my hat all using different patterns. The label is out of some of them, so I don't even know the pattern names used in some of the garments. Seems to work just fine, though.
I did not deliberately mix 'em up, but rather, when I needed garments, I bought the pattern that caught my interest at the moment (sometimes it was as simple as this was the only pattern offered by the store), which results in some interesting combinations, but they are quite effective. However, like one of the guys said before, if they catch you moving it doesn't matter what camo you use, because you will be busted.
Also, I also have several wool articles, including some stuff from Ms. Asbell, which I highly recommend. I beleive plaid patterns in muted colors are just as effective as any commercial camo made.
Lastly, LongStick64 may have been joking about the deer hide camo, but that, or a coloration similar to a rabbit, would make excellent camo.
