Thanks for all the advice. I am going to a retreat with a group of friends and we will have room to plug in our irons, although one of the ladies is bringing a full size iron and we can probably all share that one. I am also taking a class through a guild, and we have been asked to bring small irons. It does seem that if everyone has an iron there will be too big a draw on the power, so probably we won't all be able to use them at once. And I did find a very, very old travel iron that still works. I probably bought it in the 1980's. The only problem with it is that the cord drags across the fabric if you're pressing anything bigger than a block. But maybe it's the best solution for now, rather than buying yet another thing that will seldom get used.
