I recently bought a sticky mat for use while stenciling on fabric. It holds the fabric while I stencil fabric paint on it. Saw that you can iron on it - all the same features as the black mat in the applique video. It's called "Grip-n-Grip", 12.5" x 17". Got it for $15.95: cedarcanyontextiles.com/
I've used a Steady Betty pressing board since the TQS HST exchange,,,,and it is one of my best tools !! Over priced I think,,,but worth every dollar to me!!. But it wouldn't be very good for use with fusible or any other glue or sticky stuff. The foam surface would stick and tear,etc....and certainly wouldn't clean too well.... no spray starching on it either. dry iron or very lite steam.. Pieces stay sq. and true with little or no distortion.
