Really appreciate all the comments particularly the ones regarding the bobbin winder. I had read a post that said nothing is harder on your sewing machine motor than a winding bobbins. I then considered purchasing a sidewinder to 'save' wear and tear on the motor.
I too purchased the ring ruler holder WHAT A WASTE, it is hard to put the rulers on and frustrating to get them off! Then someone sent me another one in a swap...so I have two unused rings now :0)
