This must be pretty old because it’s a numotype (connect the dots). It’s a little different than the cuties and has a kinda storybook quality complete with furry tail. About a quarter of my collection have envelopes but the rest are just sheets with no markings as to their origins. They also don’t have copyright notices so they for sure in the public domain.
I would like to see auto bobbin sonress and auto stop when bobbins are empty. also the idea of being able to use a cone for the bobbin so that they would not empty as fast. Another idea is to have the machine automatically go back a few stitches when there is an auto stop. More controls with the designs in the editing panels of the machines. Auto cutters are always a good idea. Auto centering of the hoop and design would be a great asset. These are some of my suuggestions.
