OK......buckram is a stiff material...Here is a definition of it from the www.....

A BOOK CLOTH made from cotton or linen, usually the former, and closely woven, occasionally with a double warp. It is filled or coated and calendered to give it
a smooth finish which blocks well and is reasonably durable. Originally, the term applied only to a starch-filled fabric; today, however, it applies also to coated and
impregnated fabrics having a heavy base. The material used to fill the interstices and/or cover the base fabric is usually pyroxylin, but it may be starch, china clay,
clay, or other nonfibrous material.

I feel certain you can buy it at a good fabric shop..like Jo-Anns or sone of the other well known shops......

The fusible shade backing is a iron on backing that you use in adhering a piece of fabric to a shade for decorative purposes...again available in a fabric shop....

I haven't made that little paper doll but it is so cute and I have often thought of trying it just for the fun of it. Let us know how yours turns out....

I had to go find both of those things for the same pattern (I haven't made it yet though!) I got them at Jo-Ann's Fabric. The buckram is in with the fusible webbings~it's just a really stiff webbing. And the shade webbing is at the back of the store. I thought they were both expensive, but I don't have anything to compare it to...Also, I asked 2 different girls before they found both of these thing, neither knew what they were and had to go out back to ask if they sold it! Good luck!
