--don't use a butter knife - it has a bumpy edge so it's not a clean cut
--do the red last - it turned my hands colors, so if I touched the white or green with red hands, they'd turn red
Next think of a holiday word - I considered "joy" "hope" "faith" "love" but settled on "believe" even though I thought it was a little long.
I hand-cut all of my letters - drew with a toothpick and then used the knife to cut into my tracings. The thought crossed my mind, "I wonder if the Silhouette will cut a sheet of polymer clay" - I didn't want to ruin my machine with the experiment, but if anyone tries it, let me know!
At this point you'll want to etch out "2010" on the back - I am kicking myself because I forgot! Here's a sample of how I did it last year:
After baking I added some glitter for that extra fab - it looks more glittery in real life than in pics, but you can kind of see it here (the red and the white have glitter - I left the green plain):
these little flowers!)
Hang on your tree and enjoy your creativity!
Oh, and this is a really thrifty project - each pack of polymer clay at Michael's was about $1.30 - I didn't use even half of each pack - I think you could make 3-5 ornaments with only purchasing one white, one green, and one red clay block. (And obviously even more for a shorter word.)
