For the time being, this is my favorite way to preserve a pattern piece. I apply cheap fusible interfacing to the pieces I plan to use over and over again. This allows me to:
- manipulate the pattern on my body or a dress form
- fold it for storage and not need to re-iron when I use it again
- save $$$--this is the most economical choice I've found.
I buy the Pellon 15-inch wide x 3 yards long pre-packaged fusible interfacing when it goes on sale. Hancock's recently ran a sale on these packages for $0.77 USD/package.
