There are white noise apps for your phone. I have been using an app actually called white noise on my android for years. Since it is on my phone I can take with with me and use it regardless of where I am sleeping.

Before i found the app I had a small 6 imch fan I would run at night to make my white noise.

Make a square knot.

When you initially cross the laces to make the first knot note which lace was on top. Did you tie right over left or left over right. Then for the 2nd knot with loops do the opposite.

For example if the first knot was left over right then the 2nd knot should be right over left.
