Norah, Peggy, and I are making them and sending them to the Soldiers in the 120 degree heat. However, I tried the first one out that I made. I wanted to be sure that it wouldn't burst, that it had enough crystals to be comfortable, etc. etc. They work wonderfully. I wore it around my neck to mow the lawn in 90 heat, it kept me comfortable. I would suggest them for anyone living in extreme heat. Make them for family to match the quilt you're making them. Or make yourself one, they are worth their weight in gold to the men in the heat zones and to all us southern gals and guys! :wink:
