I finally managed to thread this vintage Kay an Ee Sew Master vintage toy sewing machine, but cannot seem to get it to create a chain stitch. Perhaps it is threaded wrongly; the bottom loop does not seem to ‘catch’.
Any help would be greatly appreciated!
In the search for help, this blog post came up:
Images below are from Couture Stuff blog, which now seems defunct and I have no way of contacting the author, sadly. This is how the chain stitch would look like.
