"clusters of creamy-white flowers"
Let me show you some examples of clustering I've done on my layouts.
They sit on the bottom right corner of my layout as an eye catching "cluster" of embellishments.
Co-ordinating stickease and dimensional elements from your chosen paper package provide an easy jumping off point for clustering. The flourish and pinwheel are from the Surf's Up assortment. The wooden pieces are from the Wooden accents assortment. Add some brown/tan sparkles and you're done.
Clustering is an effective way to add some punch, create visual interest, and add some texture to your layouts.
