I have had the sew steady and love it. I don't use it any longer except for retreats as I finally got a sewing table with an insert. My friend also has a Sew Ezi table with an insert that she is able to use in her sewing room and on retreats. It's really cool, packs into it's own cover and has wheels on one end so you can wheel it when you need to. I don't have any connection to this, but just wanted to let people know about it. Here's the link:
