Potential Risks of Today's Shoot

I will have to tie Sarah-jane's wrists and legs together today, and possibly put something in her mouth to 'silence' her. This could potentially hurt her and I have to ensure that I do it in a safe and comfortable way, while still looking like she is uncomfortable and cannot move. I will also have to tie her waist around a chair, meaning she will really seem like she cannot move from her position.
I will take extra caution and care to ensure that she does not suffer from any loss of circulation from the ropes being tied too tightly, or any friction burns from the ropes.
