To Knot or Not and progress

How do you secure your thread when you begin a new one? Specifically,do you or have you ever used a waste knot?
I usually use the loop method or just hold the tail down with about 3-4 stitches on the back. Never any knots except I do use them if stitching on shirts so that they last through the wash.















Today I stitched on LK August Block and accomplished quite a bit. I am not sure if I will get it finished tomorrow.
