Nice. I use up scraps whenever possible myself. I used to turn tea light holders. Nice little sellers for a while. Then it seemed no one wanted them anymore. Oh, well. I kinda liked turning them. Might do it again, now that I've seen yours.
Usually get them from one of the UK craft outlets, but those particular ones were bought in Seiffen on the east German/Czechoslovakia border when visiting the many toy making facilities there.
