It's all preference I think. I did one that was just 2 simple boutique bows stacked. I just did one with my new TOTTS instructions that was following "recipes" of a twisted boutique, spikes, twisted boutique.
I saw one I liked that had the bow "upside down" on the bottom for extra fullness but I haven't tried it that way yet. Darn kids and husband don't realize I need time to play!
