I'm going to be working on a review of the DONA Rose Petals and I'm wondering what y'all would like to see in the review.

So far I have price/count comparison between Walmart, a hobby store and the DONA line, and I'm doing the following tests:

Water float test
Soaking with water (and perfumed oil) to see if the colors run
Side by side comparison
How well they hold the fragrance when sprayed
Comparison next to a quarter

What else?
