(№.1) Start with core pieces of varying heights. The easiest display has the tallest item in the middle, making a pyramid. Odd numbers are the most visually pleasing, so here I have 5 pieces, but 3 or 7 are commonly used as well. Stagger them front to back to create depth to your display.
(№.2) Add in accent pieces, making sure that they overlap without hiding other things.
(№.3) Fill in the rest of the space with pinecones, gourds, and birds. Some things to keep in mind to help would be:
Contrast - putting light things in front of dark and vice versa
Color - similar colors should be balanced on both sides (here I have the orange gourds on both ends)
Variation - don't get stuck in a straight line. overlap, group and prop your items until it looks interesting
Impact - keep a single theme or image in mind, so people can get the idea at first glance. the details will keep them looking.
