DEFinitelhy use walking foot. Use pellon 987f but i saw walmart hard 973 (i know it was 97 something) it was a bit denser, not thicker, you could use it too, but use that walking foot. if you don't want to use the fusible on lining try Decor Bond for stiffness. Yup, it's cheap and easy to find to. it is a fusible that is pretty stiff, but not super stiff like Bukram.
Glad we could all help!!
Soooo,, where's the picture? :)
