I'm trying to tie someone up and they get squirming and getting free of the knots.  How can I fasten their ropes securely?

The best way to ensure that knots remain tied securely is to loop the ends of the ropes around the knot and then wrap them around each other before cinching the knot tight. This ensures that the knots won't come loose due to squirming. You may also want to double the amount of rope used for extra security. Additionally, you can bind the person's feet or hands to each other to further prevent them from escaping.
