Daisy, Daisy give me your answer true! Add a happy symbol of summer to the top of your Singer 221 or 222K machine or any other sewing machine! The Daisy Chain Spool Pin Doily will replace the red felt disc on the spool pin, preventing the thread spool from scratching the finish of the spool pin cover plate. The daisies are just large enough to be noticed, but will not be in the way of your machine's proper operation.
