Wow! I would have never thought of that...what a great idea! Thanks also for the link to the blog :)

Darn I"ve been doing that for at least 30 yrs.We use to travel for work and I used it in hotel rooms.I never left home w/o a machine and yardage in case there were no local fabric stores.I still use it and I"m stationary now

You can also use a plastic table cloth with felt backing they work grrrreat.
