I found these at a craft fair. Super simple design. We will be trying them for the first time in a few weeks. <img src="http://www.traveltalkonline.com/forums/images/graemlins/circle.gif" alt="" />
Thanks for sharing. We have insulated coozies that keep drinks cold for a long time. I'll have to see if engineer husband Can fix a similar thing for them. But, then, he couldn't fold the ironing board down last night! Thanks again.
