One quick tip...when using your embroidery presser foot, with your feed dogs lowered...
BE SURE TO TURN OFF YOUR MACHINE if you have a bobbin jam.
Yep, I just pierced my fingernail with the sewing machine needle. Doesn't hurt yet. I don't know how deep it went, but it did bleed some and I cleaned it and put some anti-bacterial oinkment on it, so it should be fine.
My fault for doing something on impulse. Have a great weekend!
