What is the difference in a soft cornice and an upholstered cornice?
Soft cornices are fabric and lining, stapled to a board frame. Upholstered cornices have the board padded with the fabric stapled to it, permanently. Soft cornice instructions are included in the pattern packages, upholstered cornices are not. Upholstered cornice instructions are in our "Manual Collection".

What stiffener do you recommend we use in a soft cornice?
A soft cornice should look “soft”. In my opinion, using a stiffener makes it look like you couldn’t afford a real cornice. A few ripples are appropriate. If the fabric is flimsy, use the fabric stabilizer (available from M’Fay Patterns or Rowley Co.). Also use an interlining and lining. Black out lining is an excellent choice.
