Thank you so much everybody for the kind comments on the Tin Man!
I mentioned I had been very unsure of how to tackle his face. Well, I was surfing tonight and I spotted what look like ideal faces if I wanted to do a similar project again - Yes, I know, always wise after the event! It is these Sarah Lawrence charms from the Fruit Pixie, either the Oval Face or the Moon Face. Might have to get some!
