Last nite I was rotary cutting some quilting tubes. Should have been in bed, but, hey!
So, I place my hand around the handle, push down with the index finger, and push forward.
You guessed it- pushed right down on the blade as it was beginning to move and whamo-sliced my finger. Funny thing is, it didn't hurt as much as today when my needle got upsidedown doing some hexagons. Went into the pad on my middle finger. Ouchee! Man that hurt!
