Great ideas Patricia!
Thanks to one and all for some wonderful solutions. Think I will combine a few to solve the "popsicle paws" syndrome. A friend of mine works for N.B Hydro and will get me a pair of insulated linesman,s mitts (go 1/2 way to the elbow).I shall make sure they are XL so I can fit a pair of thinsulate gloves inside. Have emailed two companies who make reusable chemical pocket heating sacs.

Thanks Again,
