craftgrrl | HAIR CANVAS or alternatives to it?

hello my fellow crafters!

I have been on a hunt for "hair canvas" to use as a form of interfacing in some of the bags that I am making and have been unsuccessful at finding any local stores or online shops that sell it. I thought of you all you right away, and thought some of you could possibly help me find a place that sells "hair canvas." OR do you have any suggestions for what can be used in place of hair canvas... seeing that is it rather expensive & i realize people can be allergic to it.

Thanks for any help you may give me!
