SuzzyQ, I think some more information and explanation is needed to be able to answer.
Did it just happen?
Had it been working correctly? If so, what were you doing - sewing seams or free motion?
If you move the hand wheel by hand do you see the feed dogs move but just below the needle plate? If so it may be possible that the feed dogs have been lowered for free motion. How to lower the feed dogs for darning is on page 62 of the pdf manual available at singerco.com.
Is this a 'new to you' machine?
Did you recently remove the needle plate to clean all the lint that has a way of accumulating there? If so, is it put back together correctly? The pdf manual (mentioned above) I have shows on page 17 the caution note about getting it back installed correctly.
Sometimes just perusing the manual helps. The page numbers above are of the pdf not the actual manual.
