This is a machine embroidered design available from Perfect Little Stitches. They have many designs available on CD for the most popular computerized embroidery or sewing machines. The CD for this specific design is $10, though you can get a CD with all their sewing-related designs for $75.
I like this particular design because it (1) doesn't look cartoonish, and (2) it looks similar to a sterling thimble that I have. There is also a design for a toy Singer sewing machine like one I have (albeit in blue: mine is black) that my late, sainted mother bought for me for a quarter* when I was a little girl. They now sell for about $300.
