Here is a link to one I did awhile back ( actually did several but this one is posted right here)

This one is wool on wool. I used Valdani Pearl Cotton for the applique - it was SO much better than embroidery thread. I also used an Iron-on fusible webbing that I would not do again. It was unreliable as far as keeping the pieces in place and made the pieced stiff. If I were to do another one now, I would either use either the tiny applique pins, small dots of Elmers/Eileens or glue stick in that order to hold the pieces in place.
I had a blast doing it and loved it, It was portable and the results were pretty good!!
