I lost my needle clamp screw at a quilt retreat but luckily someone had a spare for the same brand machine so I was saved that time. I decided then to make sure I had spares of such items like screws, needles, scissors, etc. so I'm not placed in that position again. I was amazed how expensive a little screw is though.....$10 and here I thought I was being generous paying her $10 for the screw she gave me.
