Okay, just getting into brush shaving, and I don't have a stand. What is the best way to let the brush dry? Hanging bristles down, Setting with the bristles up or laying on it's side? Thanks, Kevin
Not necessarily true. Here is the result of an experiment I did weighing two different brushes after use each morning: standing upright and hanging. Each brush was weighed after rinsing out and again after 24 hours of drying. The difference in weights represents drying. I did one dense brush (Rooney 3/1 Super) and one not-so-dense softer brush (Superior Super 20mm). Standing up on the handle yielded slightly better drying, but I'm not sure the difference is statistically relevant. Conclusion: it probably doesn't matter, so: 1) don't add it to your "must have" list because you need it, but only if you want it; 2) if you have a gorgeous gold-plated brush stand or one to match your velvet Elvis painting, no harm to your brushes. 3) if you want to get rid of that butt-ugly one your mother-in-law gave you, ignore statistical relevance and claim scientific proof to your wife as justification.
In spite of gravity, capillary action will 'wick' away the moisture whether the brush is stored bristles up or down.
As others have said, shake it out first.

The good news is that you have excellent data. Variance is very low. This is good news. As such, I'm pretty sure if there was a difference, you probably would have found it.
I did an unpaired t-test, as although the studies are crossed over, they are NOT really.
For the Rooney, there is NO difference at an alpha level of about 0.05. (I assumed t was about 2)
Confidence interval 0.05 +/- 0.086. No difference shown.
For the Superior, there was no difference... but it was MIGHTY close!
CI = 0.45 +/- 0.45. This is as CLOSE as you can get to showing a difference, without showing one. In fact, i reckon if you pulled the data, you probably would show a difference.
It's a good idea to have two or three brushes (or a lot more ) and make sure that no one brush doesn't get a couple days' rest in between uses.
