Ok, I get it now. The wonder of the felted clogs comes from knitting the "ugly duckling" and knowing or hoping that it turns into a swan.
I'm on the first one and have gotten to the upper. It, so far, has been an interesting project. Once you decipher how the pattern reads it is fairly easy to do.
My thanks to Marty who is behind me (and I mean on this project) he has done some pairs and is a good source of help.
