interfacing wonders...

[mere1312.livejournal.com]

Can someone give me a quick rundown on the basics of interfacing? It is onlt an iron on material, correct?m To stiffen areas which need to be harder. Now, I've been looking at some and it seems awfully expensive, but I don't know if I'm even looking for the right stuff. I have never used it before but I think I'm going to need to use it on an upcoming purse project.

Anyway, one more question. Does a liquid fabric stiffener do the same thing?

Thank you SO much in advance!
