I got my finger sewn when I was making my lone star quilt. so do be careful and yes the needle is sharp and mine missed the bone, but part of my finger tip is missing. Nothing got on the quilt so I was happy about that. Took a little over a week for it to start healing. I can feel it if I bump it still, but no real feeling in the tip as I can feel the cards when I play a game of solitare and such. Take care and have a great evening, Huggies, Fay
