My friend's grandfather, from Alberta Canada, carved this miniature tea set in about 1955. He was born around 1885, so would have been about 70 at the time. He carved these only when they were green, after supper while he listened to crop and weather reports on the radio.
He made them for grandchildren and other children that he met.
That's all that I know how about this little project.
I searched Google images and found that there are many other tiny ornaments, made from peach pits.
