I think you can order some attachments from Jiffy that will do the job (they have a very helpful help line), but I went to the hardware store and told them what I wanted to do and they sold me the appropriate tubing and clamps for a couple of bucks. If you find a nice old-fashioned hardware store, they will get very excited about being able to "invent" something new! I also fashioned a contraption I call a steam box, which is a plastic box with a hole in it for the steam tube. I put a hat body or a wad of Sinamay in the steam box, turn on the steamer, and it is nicely steamed in about 30 seconds. I put a gasket around the hole in the box, but it seemed to get too hot. Having it not quite airtight is probably the way to go. Of course, I was the kid who was always blowing up the chemistry lab in school, so take my advice with a grain of salt! Steam is very hot.
