Creating a horizontal stripe pattern

Questions
1

I would like to know if there is anyway to create a horizontal stripe pattern. I tried making a continuous s pattern but it did not work. Is it because parallel lines in the same function will be undefined due to not passing the vertical line test?

Here’s my version also using a list, but used lines instead of inequalities with adjustable line thickness.
