Sorry to hear of your sewing accident.
When I was 4 yrs. old, I think, I was in the house by myself and wanted to mend a sweater of mine that had a hole in it so was trying to use my mom's treadle machine while she was outside....well my finger got caught and the needle went straight thru my finger.....I started screaming and my mom came flying in the house and had to rush me to the dr.......a day I've never forgotten.
Later in life I nicked the side of my finger by getting it too close.
I feel your pain.....ouch.....
