Oh, honey, you have SO come to the right place!
Do a search for either "FT felted clogs", "felted clogs" or... read through KellyK's postings - her blog is great, too! Kelly is the clog queen and could probably teach a course by now!
And yes, you have to buy the pattern! They look super easy and all but... I have never seen anything like this pattern and I've been knitting for a while.
Good luck and welcome aboard!
