Kimono Fabric Applique Advice Anyone?

This is a quick post to see if any of my lovely, crafty readers out there can help. A friend of mine has recently asked if I've come across a good reference for using kimono fabric in applique. Sadly, I haven't, and a search hasn't turned up anything either.

In the store this week I have one obi piece that has been appliqued and I can feel that they've used an iron-on interfacing behind it.

I've never appliqued before, so wondering if anyone out there in blog-land can offer any advice or know of any good resources. Kimono fabric of course comes in many different types, so it might even be a good general applique resource that talks about the use of different fabrics.

Any help would be much appreciate!
