Sewing Machine Broken!

While sewing my last couple projects, I spent a decent amount of time screwing and unscrewing the sewing machine feet. I've been toggling between regular straight sewing and free motion quilting.  With the free motion quilting, I use a different foot.  The last time I was unscrewing, the top of the screw fell off in my hand!  The last thing I was going to do today was to sew across the little tree ornament in silver.  Instead of waiting for my new screw, I sewed it by hand.  I will be contacting my local Viking store and getting a replacement soon.
