I have a devil of a time remembering how to spell this word. I keep putting the letter L in the middle of the word. Maybe using a visual image will help on this one. The letters T and L are the highest letters in the word. They are also at opposite ends of the word. If I envision them as my arms using the towel to dry the body this may help me remember their positioning.

Bad: Towles

Good: towels

If you have a mnemonic a suggestion on how you remember the positioning of the L on this wonderful word, please feel free to share it. Thank you.
