Good thing today was practice on my treadle, I put my finger where no one should, to straighten the fabric (under the screw for the needle) at the same time I pushed the peddle Yikes a chunk of finger missing and blood a pourin! It was a small practice piece as I was working to adjust the tension. But yikes it coulda been bad on a quilt! I have also poked myself alot hand quilting and spit it is most of the time to remove it, don't worry I wash them!! LOL
