Is there a rule of thumb for the number of loops a fondant bow should have? Also, How long should you make each loop (ie. if the cake is 8" should each loop be 8" before it's folded)?

I usually make 20 or more loops, just incase a couple break, and its WAY better to have too many than not enough!! I would probably make the strips 6" long for a 8" cake. That way you get to see the top of the cake a little bit....

I don't think there's a rule of thumb as to how many you should use...When I do bows, I make a lot and then keep sticking them on until I get the look I want. The smaller and rounder I make my loops, the more I use. The longer and flatter the loops, the fewer I use.

For an 8" cake, I probably wouldn't want the bow to be more than 6" in diameter.

Thanks for your suggestions! They were very helpful.
