Just wanted to comment that both entering and turning movements can be done without elbows ever coming near faces. It's done by taking wider angles than the more classical movements. I've seen entering movements taught where the entering was almost a 90 degree movement off the line rather than the nearly 0 degree movement being discussed. Much more receptive than the classical form as well but I seem to wind up on the ground so I've bought into them. The wider angle also seems to work better with stiffies. As to turning movements Aikilove already went there.
I would try and describe the movements but I just realized I've spent 20 minutes trying and failing. Guess this is why I prefer to just practice.
