I'm just about to go shopping and knew that there was something missing from my shopping list but I couldn't remember what is was. I now know that it's baby powder (which I use on my 'more delicate parts' after washing) that I'm running low on ;-)
I use talc every day when I get dressed. Talc is useful too when you have been on the beach and got sandy feet, it helps to remove the sand really quickly.
I have several stored talc dispensers. Desperate children and now grandchildren resort to them for gifts. There must be a use for them these days, but I haven't found it yet. Fortunately oldest granddaughter has cottoned-on to my need for a handbag-sized diary and now comes up with one every Christmas. That is useful. :)
I've used baby powder for as long as I can remember....not on my body, but I use a sprinkle of it on my yarn when I'm knitting.It just seems to help it flow better through my fingers and over the needles.
I agree with the knitting wool tip, also good if you have to put on a pair of latex gloves (not in a sterile situation) and certain areas on hot sticky days.
I did however stop using it some years ago at babies nappy changes on advice, still used on their little bodies though.
