Select-A-Size Paper Towel, Print, 2 Triple Rolls = 6 Regular Rolls, 2 Count

Q: How do you install these to a ceiling fan?

I'm thinking there is not enough information. Is this a five blade ceiling fan? If so, you have clearly bought the wrong amount of paper towels, as 16 is not divisible by 5. It actually requires a 60 pack of toilet paper rolls, 12 per blade. Make a paper mashie and apply to blades, and it will be magical.
