For me - I need to wear shoes in my sewing room. Every so often I find a pin on the floor and I do not want to find it in my foot. When I was 10 I sewed my left index finger - so I am good at keeping my fingers out of the way. An I prefer to use the Clover clips or glue over pins. But have had a needle break and go flying, luckily I do wear glasses but agree it may be something to consider for those who do not wear glasses.
