I promised to post pictures of the finished bust and here they are. I LOVE FIMO Air Basic. I like that I could wrap the piece and leave it to work on the next day. I liked the way it felt in my fingers.
I got some pretty awesome tips from my friends on the interweb before I started working on this piece. I think the most valuable piece of advice was to use vinegar on the final smooth out on the wet piece. It apparently changes the clay chemically and allows for a virtually crack free dry. I had some superficial cracking and filled those by coating the crack with vinegar and smudging more clay into the crack. I finished by smoothing more vinegar over the area and letting it dry again.
It's been a blast to get my fingers mucky.
