Skeeter,
I have done this for myself for many years now. The best solution if you can find them is 100% cotton baby socks. If you can find these in a store you can use the directly with no modifications at all. Simply slip it over the end of the iron and secure it in place. To secure it I use a piece of 18 gauge solid core wire, just wrap it around the handle and sock and it will keep the sock tight on the iron.

If you can't find the baby socks (this has happened to me several times) I make my own. I found some cotton baby diapers. I spent an afternoon with the sewing machine and I make about 30 socks up. Those have lasted my for about 4 years now, and I still have some left. My sewing isn't going to win any awards, but it was enough to make up the socks. ..

Hope this helps

Ken
