The machine has no bobbin; it makes a chain stitch, and a very nice one at that! In this photo you can see the stitch on the top side. I turned this practice piece upside down to show the chain stitch as it looks on the backside (as indicated by the arrow), it's a little thicker stitch underneath but equally pretty. I am impressed by the engineering that went into this machine as well as the longevity, with NO maintenance whatsoever over the years that I have had it, for it to pick up and stitch so effortlessly this morning is a terrific testimony to a well built machine. It still could use an adjustable seam guide, I'll have to order one; it was an original attachment that screws down into a threaded hole in the bed and will be helpful when the grandchildren use it to keep the edges straight as they crank the fabric though.
I needed the assistance of additional lighting to thread the needle, I'm sure a child's eyes could handle that task easily without one. But, the thought occurred to me when I pulled out this flashlight, if we have a power outage in the future all is not lost... now I can still sew!
Life is Good!
