Hello Ed,
The only threading instructions I have for a toy machine is: The Betsy Ross. I also have a manual for the Kayanee machine.
I am happy to forward these to you if you think they might be of help to you. Please send me an email request to:
[email protected] and put Betsy Ross and Kayanee in the subject.
Thanks.
Irene "
