I just bought Pellon Peltex #70 Ultra Firm Stabilizer at my local Hancock Fabrics. It's a white polyester sheet good that is non-fusable, machine wahsable, and is "easy to cut/sew--even when sandwiched between other fabrics." The material's literature claims that this will not flatten out or be distorted by steam pressing and can be washed or drycleaned.

Will this work in place of Hymo or hair canvas? The cutter at Hancock's had never heard of either, but I explained their purpose. She said I could return this, if it's the wrong stuff. I'm just hard pressed to spend $10.95/yd plus $12+ in freight, if I can get a suitable substitute locally. Your thoughts?
