I suddenly discovered a very effective way to keep my whistle warmed up and ready to play. You guys don’t have the option, unless of course you are into cross-dressing. 
I suppose a turtle-neck will make it more difficult, but the crew-necked shirt last night afforded ready storage, reasonably effortless extraction, and some degree of concealment (whatever that’s worth). I can’t for the life of me understand why this didn’t occur to me before. Although, I suppose there were those who were even more convinced I’d finally gone 'round the bend, and off the brink. 
Oooo, kinky!
smack’s self in forehead
Sometimes I’ll keep a whistle warm by keeping it under my beer gut when I’m sitting. Sometimes my armpit. Probably keeps people from wanting to play them…probably works in reverse for you and your crewneck annie 
that reminds me of the time I kept a recorder in my armpit to keep it warm before I played it in the recorder choir in church. The traditional Unitarian Universalist joys and concerns had few people and short comments, so when I was up front I made an aside I was keeping the instrument warm; the instrument under my arm was not there out of eccentricity on my part. One of my fellow recorder players pointed out that just playing the recorder was a sign of eccentricity in and of its self.
A lot of times, I keep my high d whistle up my sleeve during winter months. Keeps it warm and close by in case a tune comes up that I can play along with. Other times, since ussually I am wearing a kilt, (OK I ussually have a GHB at the local jam) I just place it in the waistband. So any other ideals that you might come up with similar would probably work.
Somehow i think the ‘attraction factor’ is um… well… sagging in direct proportion to gravity’s cumulative effect on aging body parts. .. though my hubby wisely assures me otherwise.
At last weekend’s tionól, wandering from room to room for the 4 simultaneous sessions, an assortment of D and C whistles tucked into the front of my pants beneath my sweater stayed warm and handy. Of course, seeing the bulge, a friend declared, “Is that a whistle in your pants, or are you just happy to see me?” 
Annie, do you also keep low whistles, er, handy? That could be pretty spectacular.
oh my…
BWAAAHAHAHAHAHAHA!
Naw Annie, it’s not the " seen one seen em all " routine with those. It’s more “seen one, wanna see em all”
I’ve never seen so many whistle players blushing! Annie, perhaps you should call Guinness and see if you can get in their record book
Why no pictures in this thread? don’t want to scare new users? 
I’ve been patiently waiting for pics since Annie began this thread this morning… sounds like I’m not the only one!
Reg
Now, now. We’ll have none of that. Remember where you are — this is Chiff & (ahem) Fipple!
This got me to thinkin’
I was thinking, you could stick it in your ear if you’ve a hollow head.
Then I was thinking, you know those Arrow Though the Head comical things you can get?
Wouldn’t it be fun to have a Whistle Through the Head thing for sessions?
All yes needs is a cheapo sawed in 'arf and stuck upon the arrow bits… adjusted down in sticky-outy-ness, of course.
Nope… ain’t no piccies gonna be posted by yerstruly… no sireebob… you wants a look see, you’ve gotter come to the sessions, and you takes yer chances with hubby-dearest straightenin’ out yer glasses fer ya.
By the by… it doesn’t work nearly so neatly with the low D… … not only is it more cumbersome to remove from said position, but it looks mightily odd indeed. Tis warm though! 
You’ll just have to continue to use your active imagination then, 'cause the insertion/extract process reveals nothing more than the whistle itself.
Someone finally found a use for those rolled tin whistles they sell at Colonial tourist traps!
I’m an innocent type, me. I don’t understand. 
This is worse than the algeBRA in that other thread about the rhythm and speed method.
Come on Annie, make a clean breast of it. Show us what you mean. I’m sure we’d all get to grips with … the concept … better if we had a demonstration.
Its it kinda warm in here?
I better check the thermostat.
